We try not to get overly excited by new discoveries, but once in a while there comes along a VoIP deal that probably never will be repeated. Now’s the time. Here are a Baker’s Dozen reasons why you should buy a boatload of these Nortel IP 1535 phones before they’re all gone. Just make a bid of ~$60. We’ve given you a hint below on the going rate.

WARNING: There are reports that some of the phones from various merchants do NOT include WiFi even though the ad may say otherwise. If you need WiFi, be sure to carefully read the merchant’s ad AND verify that the phone you are ordering has WiFi before purchasing.

• Nortel’s top-of-the-line $700 phone can be had for about $60
• SIP-compatible and works with Asterisk® and sip2sip.info among others
• H.263-compatible color videophone works flawlessly
• Wired and 802.11 b/g WiFi is easily configured
• Supports both U.S. and European power cords out of the box
• Speakerphone rivals the best speakerphones on the market

• One year warranty on the phones from the eBay merchant

Connectivity Options. Once you have your phones, there are almost limitless SIP connectivity options including direct connections to many of our favorite providers: Vitelity, voip.ms, Future Nine, and Axvoice. But today we want to address two other connectivity options: sip2sip.info or as an Asterisk extension on your PBX in a Flash system, both of which give you color videoconferencing out of the box.

Using sip2sip.info with the Nortel 1535. If you haven’t discovered sip2sip.info, it’s one of the few VoIP freebies left in the universe. By simply providing your name and email address, sip2sip.info will give you a free SIP a URI that lets anyone on the planet call you via SIP at no cost. In addition, all calls to numbers registered with ENUM are free as well. For example, to call numbers in the U.S. listed with e164.org, just dial 001NXXNXXXXXX. You can talk as long and as often as you like. The call can be pure audio, or it can be an H.263 video call. It’s simple to set up and use. And, once you have your phone configured with sip2sip.info, it’s incredibly easy to add a free DID from IPkall and then a free local DID from Google Voice. Then, presto, you have a local phone number for inbound calls that will never cost you a dime. If you make most of your outbound calls from a cellphone, then this is a perfect solution for a free home telephone number where anyone can reach you. And it includes a free voicemail account that will deliver the voicemails to your registered email address whenever you miss a call. We actually travel with one of these phones preconfigured with a local number in our favorite towns. When we go to a different place, it’s easy to change the local phone number. Update: You also can obtain a free SIP URI from GetOnSIP.

There’s only one trick to the sip2sip.info setup. Once your credentials are emailed to you, log into your account and change your password to a very secure but all-numeric password.

Using Asterisk with the Nortel 1535. We have a personal preference for Asterisk, and it’s a perfect fit with these phones. Just add these entries to sip_general_custom.conf in /etc/asterisk, and video support comes to life in all versions of PBX in a Flash once you restart Asterisk:

rtptimeout=120
videosupport=yes
allow=h263

Then you’re ready to set up your extensions to support the Nortel 1535. Here are the settings we use, and they work equally well with the X-Lite 4 client if you’d like to try some test video calls on your server:

dtmfmode=rfc2833
canreinvite=yes
context=from-internal
host=dynamic
type=friend
nat=yes
port=5060
qualify=yes
disallow=all
allow=h263,ulaw,gsm

Configuring the Nortel 1535. All of the manuals for these phones still can be downloaded from Nortel’s web site. With the exception of the early phones which were configured for Turkey, here is the setup that works for us with sip2sip.info and Asterisk. Our special thanks to the dozens of gurus on the PBX in a Flash Forum who assisted with sorting all of this out. If you get stumped on any of this, the thread link provided has loads of additional information.

The two buttons at the top of the phone do most of the heavy lifting. The left one is the equivalent of the Enter key on a keyboard. The right one is the Back key. The other two keys of importance are * and #. * is used to enter special characters such as the period, slash, etc. # is used to change the keyboard type: ABC, Abc, 123, etc. Be sure you always have the correct keyboard type for the type of data you are entering. Pressing the Green button twice redials the last number called. The function key to the right of the number 3 connects you to voicemail. The function key to the right of the number 6 accesses the web browser.

Before you can configure the phone, you have to log in as Admin (Menu, Settings, System Settings, Admin, Login). The password is 1234. Then back out one level and set your Date/Time preferences. The most important one is to enable Network Time. For the Server Setting, enter time.nist.gov for a reliable NTP server. Then back out a level and choose Enable.

You’ve got to set up network connectivity before the phones will work obviously. They come preconfigured for a wired connection with DHCP support. That’s a good way to begin. Once everything is working reliably, you can switch to WiFi if desired. The only trick to WiFi is that you need to set your WiFi Type (Menu, Settings, Profile, WiFi, Settings, Wireless Settings, Authentication, Type) and then the WiFi Password for the chosen type before choosing your WiFi network (Menu, Settings, Profile, WiFi, Settings, Wireless Settings, WiFi Scanning). Once you have those set up, back out one level and choose Apply. Then back out one more level and choose Enable. You’ll be prompted to confirm you wish to restart the WiFi network. Then you’re all set.

Now you’re ready to configure your VoIP settings (Menu, Settings, VoIP Settings). Start with the domain of your server: sip2sip.info or the FQDN of your Asterisk server (Menu, Settings, VoIP Settings, Misc., Domain Name). While still in Misc., adjust the Codec Priority for video (Menu, Settings, VoIP Settings, Misc., Codec priority, Video). Choose First and change it to None. Choose Second and change it to H.264. Then choose First again and change it to H.263. Asterisk only supports H.263 so it has to be the first priority, or video won’t work. Then back out until the top left of the screen shows VoIP Settings. Choose User Information and enter your username for Username, Display Name, and Authentication name. For Asterisk, it’s your extension number. For sip2sip.info, it’s your 10-digit number beginning with 223. Enter your account password for Authentication pwd. Back out to VoIP Settings and enter the IP address of your server for Proxy, Proxy Address. For sip2sip.info, it’s 81.23.228.129. For Asterisk, it’s the public IP address of your server. While still in Proxy, choose STUN. For STUN Server IP Address, enter 75.101.138.128. Then Enable the STUN Server. Finally, back out to VoIP Settings again and choose Registration. Set the Expiry Timer to 3600. Then choose Register to connect your phone to your desired server. Done!

Using sip2sip.info with Asterisk. We were so impressed with the simplicity and functionality of sip2sip.info that we decided to also set up a sip2sip.info trunk on our Asterisk server. This is a very secure way to enable a SIP URI on your Asterisk server without exposing your server to SIP vulnerability. The only additional step with PBX in a Flash is to lock down external SIP access to the IP address of sip2sip.info. For setup instructions, see this thread on the PBX in a Flash Forums.

Configuring Voicemail Access. It’s easy to configure these phones to access any existing voicemail system. The only trick is that the number to call for voicemail access must be all numeric. On Asterisk systems, this means *98 won’t work! So, in FreePBX, first set up a Misc. Destination called Voicemail-Read and use *98 as the Dial String. Then set up a Misc. Application called VoiceMailRead and enter 86245 as the Feature Code. Then choose Misc Destination: Voicemail-Read as the Destination.

On the phone, choose Menu, Settings, VoIP Settings, Misc., Voice Mail, Voicemail Number and enter 86245. You can leave the Mailbox ID and password blank on Asterisk-based systems, and you’ll be prompted for them. Or you can fill in either the mailbox number or both the mailbox number and password, and your entries will be passed to Asterisk to access the desired voicemail box.

To access Voicemail from the phone, press the function key just to the right of the number 3 on the phone.

Using the Nortel 1535 Browser. While it’s not the best browser on the planet, these Nortel phones do have a decent web browser that can be used to retrieve current content such as news, weather, and sports scores. To set up a web link, choose Menu, Services, Web Browser, and choose one of the four links. Here are a couple entries to get you started. Others can be found in this thread on the PBX in a Flash Forums. Remember to use the Top Left function key as the Enter key in browser links! HINT: While in one of your four preconfigured web sites, if you press the Right Button just above the directional arrow keys, you can navigate to additional web sites.

• mundy.org/news.php – Latest Yahoo! News
• google.com/m – Google Mobile

To access the Browser, press the function key just to the right of the number 6 on the phone.

Accessing Email on the Nortel 1535. Both POP3 and IMAP email access are supported on the phone. And a number of boilerplate email messages already are preconfigured for sending using your chosen email provider. You can set up additional ones using the Template option. To set up email, go to Setup, Messages, Account Settings.

Nortel 1535 Organizer. These phones also include a very capable Address Book and Calendar. Entries can be imported using a standard SD/MMC card. We’ll leave the rest for you to sort out. Or take the guess work out of the experiment and read Nortel’s excellent documentation. Enjoy!

Some Recent Nerd Vittles Articles of Interest…

Ever wrestled with one of those thorny problems for weeks only to wake up in the middle of the night with the answer? Thus was born Travelin’ Man, a web- based, one-click Asterisk® application that automatically reconfigures your Asterisk PBX to enable remote SIP phone access from your cellphone, iPad, remote PC, NetBook, or desktop telephone.

News Flash: Be sure to read our latest article introducing Travelin’ Man 3, a completely new security methodology based upon FQDN Whitelists and DDNS. In a nutshell, you get set-it-and-forget-it convenience and rock-solid VoIP security for your Cloud-based PBX or any PBX in a Flash server that’s lacking a hardware-based firewall and you get both transparent connectivity and security for your mobile or remote workforce.

If you’ve read the Incredible PBX series of articles on Nerd Vittles, you already know what a thorny problem remote phone access is if you want to preserve the overall security of your server. Indeed, our recommendation has been to leave SIP access closed on your hardware-based firewall because of the dangers inherent in activating remote SIP access. Now we have a better idea!

Today’s new approach works like this. First, we’ll run a little script that secures all of your extensions with permit entries locking down all these connections to the IP address range within your private network. Then we’ll open the SIP and RTP ports on your hardware and software firewalls and map these ports to your Asterisk server’s private IP address. With this setup, no one can attempt remote SIP logins to your server because Asterisk blocks all SIP extension connection attempts except those originating inside your LAN. To manage external phone connections to your server, the install script creates a new virtual Apache web server on your Incredible PBX using port 83. We’ll enable and map TCP port 83 on your hardware and software firewalls to your server as well. Web access with port 83 is limited to running the Travelin’ Man app to activate external phones.

Now we’re ready to set up access to your server for remote devices. For each extension you wish to enable for remote access, we’ll create a special web directory using an obscure, random file name which will serve as the web link for the Travelin’ Man web app. For example, in the diagram above, directory 184778 manages extension 501, directory 2389957h manages extension 701, and directory 6993h5j manages extension 702. This is accomplished by simply changing the extension number in the index.php script stored in each directory.

When one of these web links is accessed remotely, the PHP script will automatically reconfigure Asterisk to enable access to the designated SIP extension on your server using the remote IP address from which the web page was accessed. And, of course, there’s an additional layer of SIP security as well. You still need your extension credentials to actually log in to your server with a softphone to place and receive calls. The Travelin’ Man installation process takes only a couple minutes, and the remote SIP activation procedure takes just a couple seconds each time you want remote access from a different location. Here’s a quick example of how it actually works.

Let’s assume we want to use the new $3.95 Bria SIP softphone on an iPad to connect as extension 501 on our Incredible PBX back at home. The problem is that the dynamic IP address of your iPad changes at each new site on your itinerary. Some locations have WiFi while others only have 3G connections.

First, we’ll generate an icon to run Travelin’ Man from your iPad desktop. Use the same procedure with an iPhone or iPod Touch, and there’s a similar procedure for Android devices.¹ You only have to do this once. Start up Safari on the iPad to access the new port 83 web server at the random web address the installer created to support extension 501. That web address is something like this using your own FQDN²: http://myserver.dyndns.org:83/184778. After establishing the link once, we’ll hit the + button in Safari and choose Add to Home Screen. This creates the TravelMan icon on the iPad. See the screenshot below of our demo iPad setup which used extension 221 instead of 501.

Once configured, it’s just two clicks to enable your remote phone anywhere: click once on the TravelMan icon. When your IP address is confirmed, return to your Home Screen and click the Bria softphone icon to establish a SIP connection back to your server. Behind the scenes, the Travelin’ Man application will generate the required permit entry for your remote IP address mapping it to the designated extension on your server, and then it will reload your SIP settings to make your Asterisk server accessible to the Bria softphone in your hotel room. The entire process takes only a couple seconds.

If your company happens to have a dozen traveling salesmen, then you’d simply assign a dedicated extension to each employee and create secure directory names for each person (e.g. 2389957h and 6993h5j in diagram above) with a copy of the Travelin’ Man app configured for that employee’s extension number. Now your entire mobile workforce has connectivity back to the home office from any location on the globe. And, when an employee leaves the company and another arrives, just create a new name for the old employee’s web directory to preserve the security of your system (e.g. 184778 in our example becomes 78hd773). Keep in mind that each time the Travelin’ Man app is run for any extension, it wipes out any previously authorized IP address entry for that extension. Thus, the security of your Incredible PBX is always preserved.

Prerequisites. Before proceeding with today’s install, you must be running a stock install of Incredible PBX with PBX in a Flash behind a properly-secured, hardware-based firewall³. We recommend the latest version of Asterisk 1.4 because it addresses a SIP vulnerability that might cause you problems if malformed SIP packets are targeted at your server. The current release of PBX in a Flash (1.7.5.5 Silver) is ideal, but any version of PBX in a Flash can be brought current with Asterisk using the update-source and update-fixes tools. Travelin’ Man assumes that you have the Incredible PBX base install of extensions: 501 plus 701-715. You can obviously add more or remove some, but you’ll need to manually adjust sip_custom_post.conf to reflect your actual extension list after the install completes.

The installer has been encrypted for your/our own protection. In source form, the script would allow anyone to defeat the Incredible PBX requirement. Doing so would mean the required IPtables security component would not be in place and properly configured to protect the underlying system from attack. So we’ve opted to play Big Brother to avoid potential security problems for all of us down the road. This article clearly explains all the necessary components if some folks want to roll their own version. We just don’t want the responsibility if something goes horribly wrong. As Forrest Gump would say, "Shit Happens." If you don’t believe it, check out the latest security scramble in the trixbox forums.

Installation. Now we’re ready to get started. So log into your Incredible PBX as root and issue the following commands:

cd /root
wget http://incrediblepbx.com/travelinman.tar.gz
tar zxvf travelinman.tar.gz
./travelinman.x

NOTE: If you’re using PIAF2 with CentOS 6.2, you’ll need to use the updated version of Travelin’ Man because of a syntax change in the Apache config file:

cd /root
wget http://incrediblepbx.com/travelinman2.tar.gz
tar zxvf travelinman2.tar.gz
./travelinman2

The first step in the install procedure is to lock down access to all of your extensions to your private LAN subnet. In case you ever want to do this on another server not running the Incredible PBX, here’s a link to our privip.sh shell script that shows how to do it. This should work on most FreePBX-based Asterisk systems.

Once the extensions are locked down, the script will modify your IPtables and Apache configurations to permit web access on port 83. Next, it will adjust your Asterisk setup to support the Travelin’ Man permit scheme. This involves reworking of sip_custom_post.conf so that permit settings for individual extensions can be stored in files named 501.inc, 701.inc, etc. Finally, the installation procedure will set up a single web site to support extension 501 with a randomized directory name for remote access.⁴ This setup will be stored in /var/www/travelman. To activate support for additional extensions, you would simply copy the subdirectory giving it a new random name: cp -r dir1 dir2. Then edit config.php in the new subdirectory and change the $extension entry.

To complete the install, you must reconfigure your hardware-based firewall and map the following ports to the private IP address of your server:

TCP 83
UDP 5060
UDP 10000-20000

When the installation is completed, it will show you how to access the new web site for extension 501 using either a fully-qualified domain name or a public or private IP address. Now just follow the steps at the beginning of this article to set up your Android or iDevice, and test things out. Enjoy!

Reminders: Be sure to review the comments to this article and the related support forum thread for a week or two for late-breaking enhancements and issues. Also, Incredible PBX comes preconfigured with call forwarding activated for extension 501. Don’t forget to either disable it or set up a real call forwarding number for extension 501 if you want your cellphone to ring. From any extension on your server, just dial *72501 to set up call forwarding. To cancel call forwarding and pass calls directly to the registered 501 softphone, dial *74 and enter 501. Also be aware that the default RingAll ring group (700) configuration on Incredible PBX systems does not include extension 501. So add 501 if you want your remote extension to ring for incoming calls.

We interrupt our Incredible PBX coverage this week to bring you a summer roundup of the best and worst VoIP softphones for use with an iPhone, iPad, or iPod Touch in conjunction with Asterisk®. We’ve tested all of these products with Asterisk sitting behind a NAT-based firewall/router which introduces some additional wrinkles unless your softphone and server are connected through a virtual private network. We’ll leave the VPN discussion for another day. None of these products has native support for the iPad although all will work with any iPad as will any standard iPhone app in either 1X or 2X mode.

The three four products we’ll be evaluating are Acrobits SIP Softphone, the WiFone from Snizmo.com Ltd., the Media5-fone, and CounterPath’s just-released Bria softphone. All support SIP dialing, and the WiFone provides IAX connectivity as well. We were a bit surprised that, despite their reliance on SIP to connect calls, SIP URI support was minimal to non-existent in all but the Bria product. Before diving into the individual products, we should note that, in conjunction with our product evaluations, we received no compensation or discounted/free software from any source. We are a beta site for CounterPath’s next Bria release.

Acrobits Softphone. The Acrobits Softphone requires iPhone OS 3.0 or later and was recently updated on June 3, 2010. The softphone only supports SIP but works with both WiFi and 3G connections which makes it a perfect complement to current generation iPhones as well as the iPad-3G. The softphone also supports push notifications for inbound calls until multitasking is available with iOS 4.0. Multiple SIP accounts can be registered, and the softphone has SIP proxy, VPN, and STUN server support, a must with Asterisk sitting behind most NAT-based routers. G.711, GSM, and iLBC audio codecs are supported in the standard configuration, and we experienced excellent call quality using WiFi with no DTMF issues. As with all of these VoIP phones, 3G call quality was all over the map depending upon the reliability of your nearest cell tower. SIP URI’s can be called by cutting-and-pasting dial strings from entries in the Contacts list email address fields provided the SIP URI destination name is numeric. Quirky but it works. There’s also a speed dial feature for your 12 favorite contacts. Flexible dial strings are supported to smooth the path for international calling. With iOS 3.1, a bluetooth headset can also be used. The application sells for $7.99 in the App Store, and G.729 support can be added for an additional $9.99. G.729 is a must-have if you’ll be using a 3G network for most of your VoIP calls.

While call quality is obviously subjective, the Acrobits Softphone was our personal favorite for daily use. We routinely use it on an iPad to check Asterisk voicemails and to make outbound calls through our home Asterisk server while traveling. Setup is as simple as entering the IP address or FQDN¹ of your Asterisk server and an extension number and password to handle the calls. We added a public STUN server entry because of our NAT-based Asterisk setup.

Snizmo’s WiFone. A very close runner-up in voice quality was the WiFone from Snizmo.com Ltd. This softphone has the added advantage of supporting both SIP and IAX2 connections to Asterisk. If security and ease of use matter most to you, then you can’t go wrong with this softphone. IAX2 connections are much less vulnerable to attack from the Internet and are considerably easier to configure because of the elimination of thorny NAT issues. If we had found this softphone first, we probably would have looked no further. As you can see from the screenshot, this softphone supports multiple SIP and IAX connections and is easily set up using the configuration menu. For our European friends, it also supports SMS using a dozen different providers. Echo cancellation and STUN support are available, and G.711 and GSM codecs can be individually configured for SIP and IAX connections. An Outbound Proxy is also available as well as support for international dial strings and prefixes if you need it.

For SIP accounts, simply provide the server address, a username, and password. Authorization name, SIP port, and proxy server settings are optional. For IAX accounts, server address, username, and password are the only required entries. Each account can be toggled ON and OFF to meet your individual requirements. SMS Settings provides a listing of a dozen SMS providers. Simply add your username, password, and a CallerID and SMS just works. The contacts list also synchronizes with your Mac Address Book as well as MobileMe. The call quality of both SIP and IAX connections using WiFi was excellent. 3G support is not yet available. The web-based tutorial is excellent, and the application is available in the App Store for $6.99. An international version also is available.

We could not get the SIP URI functionality to work because the Contacts list phone numbers do not support SIP URI syntax, and there’s no way to manually enter or cut-and-paste a dial string from an email address in the Contacts list. While the polish of the application was not quite up to the Acrobits Softphone, the call quality was uniformly excellent with the SIP URI limitation that we’ve noted.

Media5-fone. Our final softphone in today’s roundup is Media5-fone from Media5 Corporation. It can be downloaded from the App Store for $4.99. While the application is exclusively a SIP phone, it does have preconfigured setups for dozens of providers in the event your requirements extend beyond the Asterisk universe. Unfortunately, there is no STUN support in the current version which makes it unsuitable for use with Asterisk implementations that sit behind NAT-based routers. Multiple SIP connections are supported as are second call, call waiting, and call toggle. In the current version, both SIP over WiFi and 3G are supported using iLBC, G.711, Enhanced G.711, G.722, and iSAC codecs. SIP Info, RFC 2833, and RTP Inband DTMF methods are configurable for each SIP account. Dialing prefixes are flexible and the phone has language support for English, Arabic, French, German, Italian and Spanish which facilitates international use. The phone also includes a nice implementation of visual voicemail; however, the SIP password and voicemail password would have to be the same to function properly with Asterisk. Automatic gain control and echo cancellation also are supported. With the addition of STUN and SIP URI support, Media5-fone would be a worthy competitor.

Update: CounterPath’s Bria. As luck would have it, CounterPath released their new Bria softphone for the iPhone today. It also is iPod Touch and iPad-compatible and supports both WiFi and 3G. The softphone is available at an introductory price of $3.99 in the App Store. It’s the best bargain in the softphone market. G.729 support can be added for an additional $8.99. G.722 wideband support reportedly is coming in August. You may recall CounterPath’s terrific and free X-Lite offerings for Windows, Macs, and Linux. They’ve been one of our favorite developers ever since, and we are actually serving as a beta tester for their next release. As usual, the Bria interface offers what is hands-down the best UI in the business. The voice quality of the calls is impeccable. Our only criticism is that out-of-the-box, Bria doesn’t work for placing outbound calls with Asterisk. Registration of credentials works fine, inbound calling works great, but outbound calls to either an extension, a phone number in the Address Book, or a SIP URI all just hang with no error message or notation in the log. Only after tracing down an obscure link on their web site did we discover the problem. It turns out that one simple change of a single default setting gets things working as they should. To make the change to support Asterisk, click Settings, Advanced Settings, Network Traversal Strategy, User Specified. Then change ICE:ON to ICE:OFF. Click the Advanced button, and then Apply Changes. Aside from this one default configuration glitch, the Bria softphone would be our Editor’s Choice. We highly recommend you make your purchase while the softphone still is available at the introductory price. For an excellent review, see Alec Saunder’s Blog today.

Some Recent Nerd Vittles Articles of Interest…

1. FQDN = Fully-Qualified Domain Name [↩]

With apologies to Arnold’s infamous line, all we can say to iPhone enthusiasts of the world is that once you try this Android phone, you won’t ever go back. Google has done for the mobile phone what Apple did with Mac OS X except Google also opened up the hardware platform. Unfortunately, Apple opted for locked and proprietary hardware and software in rolling out its iPhone. Now that the second-generation Android phones are appearing, the difference is palpable.

Update. There’s now a third-generation Android phone that’s even better than this one. You can read all about it in our latest article.

Choosing the World’s Best Cell Phone is obviously fraught with peril. All other things being equal we would have bestowed the honor on Nokia’s E71 which we reviewed recently and have personally used until a month ago. That’s when we jumped into the Android World which we will tell you up front is still a bit of a work in progress. But, all we can say is WOW! The openness, the technology, and the creativity showcased in the new Android phones point to an inescapable conclusion. Google once again has struck the Mother Lode. Seeing is believing as they say. And today we’ll digress from our usual format to bring you a pictorial tour of the HTC Magic. No. You don’t have to carry a white one like Arnold. Heh. A shiny black one is readily available. We actually had planned to walk through the process of rooting the phone, but we’ll leave that for another day primarily because this mobile phone provides sufficient flexibility in its native state to deliver an almost perfect cellphone experience even without root access.

We’ve already covered our objections to the iPhone in a previous article so we won’t repeat them here other than to note that SIP clients can’t run in the background on an iPhone which makes them next to worthless for inbound calls. Yes, there are kludgey workarounds, but these open yet another can of worms. We’ll dispose of the Nokia product line by telling you they’re headed in the wrong direction just like Microsoft with the wrong operating system(s), the wrong product design, and the wrong technology mix. Just when the world is finally looking for a mobile platform that provides flexibility in transitioning between the cellular networks, WiFi, and WiMax, Nokia kills the SIP stack and SIP client on its entire line of new cellphones. So a company that once was THE innovative cell phone manufacturer in the world suddenly is looking a bit like Yahoo, lots of thrashing around but no cigar. Sadly, it’s mostly the result of self-inflicted wounds. But we’re not going to dwell on the past today. We’re going to look at what the future holds in mobile communications. And the one word that best sums up our hopes for future mobile telephony is Google… more precisely, Google’s totally open source Android Platform.

So let’s again go about this by the book… with a requirements analysis! You can match it to your own wish list. We want a cellphone that makes cellular calls from most locations, and we want the ability to decide which cell provider we use depending upon where we are. We want the option to make phone calls through our own SIP provider, or Asterisk® server, or Google Voice whenever we feel like it with or without a Wi-Fi connection. And, of course, we want VoIP Prioritization. This means we want our cell phone to prioritize incoming and outgoing calls by attempting to use VoIP services first, cellphone carrier second. We also want to be able to check our email using gMail, POP3 and IMAP servers at 3G data speeds. For the business community, we also think Microsoft Exchange support is indispensable. When we need to send or receive something on our notebook computer and there’s no WiFi around, we want our cellphone to provide data connectivity. We’re not going to be downloading movies and 1,000-page books all day long. We just want to get an important file attachment from the office so we can read it on a normal screen. If the cellphone provided a PDF viewer, so much the better. And, finally, we’d like a QWERTY keyboard for messaging, and we want to be able to change our own battery, add a memory chip, and swap out SIM cards whenever we’d like. We also want the ability to gain root access should we ever wish to do so. After all, it’s our phone! Bluetooth for phone calls and A2DP for music in the car would be great, and a good camera as well as GPS functionality would be nice to have on the phone as well. For those in the U.S., we’d add one additional requirement: support for AT&T’s 3G network so you’re not stuck with T-Mobile’s dog-slow (and incompatible) wireless data network. Most of the Android phones currently flunk this test leaving you with nothing but EDGE service if you use a provider other than T-Mobile. Of course, with T-Mobile, you get mostly EDGE service in the U.S. as well.

And the winner is…

Our pick is the unlocked Rogers HTC Magic phone, the only Android phone that we could find which supported rooting and AT&T’s 3G network in the U.S… albeit from a Canadian provider. That’s the price U.S. consumers pay for a government that continually rewards the telephone oligopoly with exclusivity rip-offs. So how does the HTC Magic stack up to our wish list? We’d give it a 94. It does everything on our Wish List… and more. The images which follow incidentally were taken using the screen capture utility that’s part of the Android 1.5 SDK. It is easily installed on either a Windows or Linux PC or your favorite Mac (except Snow Leopard for the moment). There’s a great tutorial on how to install the Android SDK as well as a YouTube video and tutorial on rooting the Rogers HTC Magic phone should you desire further information on those topics.

Getting Started. Before proceeding, set yourself up a Gmail account if you don’t already have one. As with most provider-specific cellphones, this HTC Magic phone is hard-coded to the Rogers network in Canada. Assuming you want to use AT&T’s network in the U.S., step #1 is to enter AT&T APN settings when you first turn on the phone. After inserting the AT&T SIM and booting the phone, press the Menu key before doing anything else. Next click Add APN. Enter the following values leaving the remaining fields blank:

Name: att
APN: wap.cingular
Password: CINGULAR1

Now press the Menu button again and choose Save. For other providers, try this Google Search.

Main Screen. Once you’ve entered your Gmail credentials, the phone will boot and display a Main menu. It actually is three screens wide. You can move to the other screens by swiping your finger to the left or to the right. You’ll notice a thumb tab at the bottom of the display. By dragging this up, you can access all of the other applications on the phone. Move it back out of the way by dragging it back down or pressing the Back button (←) which is the third from the left button just below the screen display.

Applications. Here’s the first page of our Applications. You scroll through the list using the trackball, or you can drag your finger vertically on the screen to reposition the display up or down. Tapping on an entry starts the application. Pressing the Home button on the far left just below the screen display returns you to the Main Screen. Every app is displayed in this listing except for Widgets. Widgets are more like scripts and typically are used to toggle functions on and off. In the left Main screen above are four widgets to toggle WiFi, BlueTooth, GPS, and Ringer/Vibrate/Silent functions of the phone.

Android Market. All of these applications didn’t necessarily come with the phone. Google’s Android Market has been set up for developers to display their wares. You can become a developer, too. And, unlike the iPhone apps, most of the Android apps still are free. Just another advantage to open source technology. To access the Market from your phone, just choose the Market app and follow the intuitive menus. There’s a great Search function. Again, unlike the iPhone, these applications get stored on a MicroSD card. A 2GB card comes with the phone. Do yourself a favor and start with a $50 16GB card.

Messaging. As you might expect from Google, the Android platform excels at messaging of all flavors. Whether it’s text messaging, Gmail, or POP3/IMAP email connectivity, Android has you covered (see above). And the support for Microsoft Exchange is nothing short of brilliant. In the social networking department, there’s full-featured support for Twitter and Facebook, among others. Using the Search function in the Android Market, you can have your phone set up with your favorite tools in just a few minutes.

Android Security. Securing your phone is also nothing short of brilliant on the Android 1.5 platform. Simply draw an unlock code pattern using your finger, and that becomes the signature for future access to your cellphone. Also works pretty well as a sobriety test. If you can’t unlock your phone, don’t unlock your car! You also can lock your SIM card to your phone and set a password if you’re nervous about losing your $500 crown jewel. What the security system really demonstrates is that the open source community has nothing to apologize for. The quality of this software is every bit as good if not better than the software produced by the other cellphone players.

Placing Calls. Yes, we hear you. What about making phone calls? You’ll be pleased to know that the HTC Magic can do that, too. We were just saving the best for last. In fact, this phone can make calls in three different ways: through your cellphone provider, through SIP using your Asterisk server or another provider, and through Google Voice. Once you install the Google Voice application from the Android Market, simply configure it with either your cellphone number or an intermediate provider such as SIPgate or IPkall. You then have a choice of whether to make Google Voice the primary or secondary calling source. Or you can choose to be prompted for each call as shown above. Google Voice calls that go out through your WiFi data network connection incur no charges in the U.S. and Canada.

SIP calls are placed using the SIPdroid application which also is available in the Android Market. Shown to the left is a sample setup for SIPdroid to connect to your Asterisk server on a private home network. In the SIPdroid Call Options, specify whether to use WiFi and/or 3G/EDGE for the SIP calls. And set a preference for how your calls should be placed, i.e. cellphone carrier or SIP. The only tricky part is the Extension Settings on your Asterisk server. Just create an extension in the usual way using FreePBX. But make sure your settings include the following entries: canreinvite=no, nat=yes, and qualify=no.

To route outbound calls through SipDroid instead of your cellphone provider, just append + to the end of the phone number. You can generate a + symbol on your phone keypad with a long press of the 0 button.

Android Backups. No article would be complete without some mention of backups. The Android platform currently supports four options: Android images, MyBackup, and Google and Exchange Synchronization. Android images can only be created if you gain root access to your phone or load a different image on your phone. MyBackup is a $9.95 app from the Android Market that lets you backup your Applications and Data separately onto your MicroSD card. Unless you’re a techie, it’s well worth the money. Google and Exchange Synchronization you will find under Settings, Data Synchronization. With Google Sync, you can back up your Gmail, Calendar, and Contacts data automatically and as a background task. Be sure to activate it. Finally, you’ll see displayed above a browser display from mundy.org/whereib that you may find helpful from time to time. It displays not only a map of your current location based upon your IP address, but also shows your public IP address.

Android 3Gtest. We’ll leave you with a hot tip about one additional application: 3Gtest. Just download and install it from the Android Market and then run it. You’ll be amazed by the results. Not only will it tell you how good your upload and download speeds are, it also will tell you some interesting tidbits about whether your provider is living up to their oft-repeated promise of Net Neutrality. Our download 3G speed in Charleston, South Carolina was actually close to T-1 performance. Interestingly, our upload speed was pitiful… about as fast as a circa 1860′s telegraph machine.

Android System Backup. We said we weren’t going to cover rooting your phone, but we do want to point you in the right direction and also show you how to get a perfect image backup of your phone. If you’re not comfortable entering system commands, stop here! We are Mac snobs so what follows is the Mac way of doing things which is incredibly simple compared to the hassle with Windows in getting the correct USB driver loaded to make things function properly. If you’re determined to use Windows, be sure to install the Android SDK before you connect your phone to your PC. And read up on how to install the appropriate USB driver for Windows. With a Mac, all of this just works… out of the box. As we mentioned previously, we’ve only tested this with Leopard and Snow Leopard, and Snow Leopard does NOT work!

Before proceeding, you must enable USB Debugging on your phone. You’ll find it here: Settings->Applications->Development->USB Debugging

To get your Mac set up with the proper toolkit, do the following. There’s nothing tricky here. Just don’t skip any steps. And you only have to do this once! First, download the Android 1.5 SDK for the Mac from here. Unzip android-sdk-mac_x86-1.5_r3.zip on your Desktop and rename the folder to android-sdk. Now drag that folder into your Applications directory. Next, open a Terminal window and create/edit .bash_profile: nano -w .bash_profile. Add the following entry: export PATH=${PATH}:/Applications/android-sdk/tools. Then save the file: Ctrl-X, Y, Enter. Now run the same command from the CLI prompt to update your PATH now: export PATH=${PATH}:/Applications/android-sdk/tools. Next, download fastboot-mac onto your Desktop from the HTC Support site. Unzip the file and rename the file to fastboot. Then, download recovery-new.img to your Desktop. Drag both fastboot and recovery-new.img into the Applications/android-sdk/tools folder.

Now we’re ready to make your backup. Plug your phone into your Mac using the USB cable that came with the phone. Open a terminal window on your Mac and change to the SDK tools directory: cd /applications/android-sdk/tools. Run the following command and make certain your phone shows up in the listing: adb devices. You should get a display with the serial number of your phone:

List of devices attached
HT95RNK02843 device

Assuming your phone shows up in the list, you’re ready to proceed with a backup. Turn off your phone. Then, while pressing the Volume Down button, turn your phone back on. Hold down both buttons until you see a screen that says <BACK> FastBoot Mode with dancing Androids on skateboards at the bottom of the display. Press the BACK button (←) and the FASTBOOT USB menu will display. In your computer’s Terminal window (NOT on your phone), type: fastboot boot recovery-new.img. Your phone will reboot and display a screen with several options in blue. Use your phone’s trackball to carefully scroll down to the Nandroid Backup 2.1 option. Then depress the Trackball button to begin the backup. You’ll see a yellow display message indicating that the backup is proceeding. When the backup completes, choose the Reboot System Now option to restart your phone normally.

You’ll find the new backup on the SD card. To copy it to a safe place on your Mac, drag down the Message Bar at the top of the display after your phone has rebooted. Tap the USB Connected Select to copy files to/from your computer option. Then tap the Mount button. A new drive NO NAME will appear on your Desktop. Double-click on it and drag the nandroid folder to a safe place for permanent storage of your backup. To unmount the phone, do it on your Mac desktop first. Then reverse the mount process we initially used on the phone to mount it. Simple!

Rooting Your Phone. We have NOT done this so you’re on your own. You’ll probably void the warranty on your phone by proceeding. The best article we could find on the procedure for rooting and restoring your phone is here. But it doesn’t have the correct backup image. If you restore the wrong image, your phone’s radio may no longer work on your provider’s network. The consensus seems to be that the proper image for a rooted Rogers HTC Magic is here. The best tutorial for actually performing the magic appears to be here. But we would stress again that we have not actually tried this, and you really, really are on your own if you proceed past reading this article. It’s your $500 phone… or brick as the case may be. Before doing anything further, we would strongly recommend you make several backup images as outlined above and also spend some time doing a careful review of the postings in this forum until you are very comfortable with all of the wrinkles and procedures. If something goes wrong, post your problems there, not here. We’re handing you the map, but it’s your choice whether to jump off the cliff. Enjoy!

Update: The unlocked Rogers HTC Magic phone used for this review is now available for purchase from Nerd Vittles. It supports 3G networks of both Rogers in Canada and AT&T in the United States. Just make us an offer we can’t refuse. It’s still a terrific phone!

Some Recent Nerd Vittles Articles of Interest…

We're wrapping up our Gizmo5 series with what we believe is the real silver lining in the Gizmo Project. Here's our YouTube demo to prove it. We kicked things off by showing you how to set up a Gizmo5 account to make free calls with Asterisk® using Backdoor Dialing and ENUM. Then last week we added an Asterisk dialplan script to actually test whether an outbound call would be free through Gizmo5 before choosing a final route to terminate outgoing calls from your Asterisk server. Today we're going to use your Gizmo5 account to transform a standard Nokia N95 cellphone into a SIM-free, carrier-free WiFi SIP telephone which can perform a whole bag of tricks at absolutely no cost... once you own the unlocked phone. It's the perfect back-to-college gift if your wallet matters. Without too much hype, suffice it to say the N95 earned PC Magazine's Editor's Choice. In a word, the call quality is phenomenal. If you like Snickers candy bars, then you'll love the size of this phone. And WiFi works all day with Nokia's Symbian OS even though you're lucky to make it an hour with Windows Mobile devices. Maybe it's not the WiFi that's the problem after all, Bill. Ooops. He retired. Sorry. Anyway, any unlocked Nokia N95 will do. Just not the N96! And you'd better get one while they last. Nokia apparently has had a change of heart on SIP telephony support, and it's quickly disappearing from their newer models. Dumb move!

SPECIAL NOTE: We have one, gently used N95 for sale. It actually was used to prepare this article. Make us an offer, or we'll make you a deal you can't refuse. If you're interested, contact us.

When we're finished, you'll have a better appreciation for why AT&T and the other cellphone carriers hate Nokia phones and why Comcast would prefer to limit your bandwidth and charge you $40 (extra) per month for their VoIP service and boatloads more for their pay-per-view movies. This isn't about greedy bandwidth abusers. It's about a greedy service provider. Comcast could easily rein in bandwidth abusers with a letter threatening to terminate service. What they can't control with nastygrams are the Blockbuster's and Walmart's of the world that want to deliver pay-per-view movies to your doorstep via the Internet. So this looks more like restraint of trade to us than protection of scarce resources from the Napster generation as Comcast would have you believe. You don't make the whole class stay after school because one kid chewed gum... if your motives are as pure as the Comcast TV barons would have you believe. Now where were we? </rant>

For openers today, you can place SIP calls at no cost to any SIP phone or Asterisk server in the world. See our previous tutorial to learn how to set this up on your Asterisk server. Second, you can place "regular" phone calls to any phone in the world using a Gizmo5 account at Gizmo5's discounted calling rates (2¢ a minute or less for calls to U.S., U.K., most of Europe, China, and Australia for example) rather than cellphone subscription plus stratospheric long distance charges. Third, you can place free calls to almost every non-AT&T cellphone in the U.S. by dialing 0101 and the number. Fourth, you can place free calls back to and through your Asterisk server to just about anywhere on the globe (except resort areas surrounded by water) for almost nothing. And, finally, you can receive free calls on your N95 cellphone whenever anyone dials your free IPkall-assigned DID in the Seattle area or your SIP number through Gizmo5. And, did we mention that all of this magic occurs with no connection to AT&T or any other cellphone carrier. In fact, we don't even have a SIM chip in our N95. Well... not all the time anyway. All you really need is a WiFi connection to make all of this work. And even the Asterisk server is optional. So let's get started.

Enabling WiFi on Your Nokia N95. Before we can use the N95 as a free SIP telephone, we've first got to get a WiFi connection enabled on the phone. Pressing Menu, Tools, WLAN Wizard will get you started. You can test your connection by opening the web browser for a trial run after you have your WiFi connection set up. Once it's working, be sure to disable the WiFi Access Point scanning feature by choosing Menu, Tools, Settings, Connection, Wireless LAN and set Show WLAN availability to Never.

Installing the Gizmo5 Application. Now the tricky part, and it's really not that difficult. It just happens that there's lots of conflicting information posted around the web, and this makes the drill more confusing than it needs to be. First, if you already have automatic registration of your Gizmo5 account on another device or an Asterisk server, disable the automatic registration. You can't have the same account registered in two places simultaneously. Just open a second account if you need it. There are two components that need to be installed on your Nokia N95, and they're in different places. First, install Nokia Internet Services Support Package to the device memory (not to the memory card). Here's Nokia's download link. Next, install the Gizmo5-Nokia PlugIn from gizmovoip.com. Here's the download link for that one. Finally, we had one little gotcha with getting everything to work once it was installed. On your phone go to Menu, Tools, Settings, Connection, SIP Settings, Options, Edit SIP Profile and set the Service Profile to Nokia 3GPP. Next, go to Menu, Tools, Internet Tel and activate Gizmo after choosing your default WiFi network. You'll be prompted for your Gizmo account name and password. Once it's registered, you should be able to dial 0101 plus an area code and phone number to test out the free calling feature. Or you can dial an area code and number, and route your outbound call as a pay-by-the-minute Gizmo5 Internet Call under the Options button. To call a sip phone directly, simply create a new Contact and insert an Internet telephone entry in the SIP URI format: sipname@FQDN.com. Once you have saved the entry, simply choose it from your Contacts to place the free SIP call. In Nokia-speak, it's referred to as an Internet Call.

If the above procedure doesn't work for you, repeat the drill and set the Service Profile to IETF instead of Nokia 3GPP. Not sure why but one setting works some of the time, and the other one works the rest of the time. If you can't connect, this is usually the problem... assuming you've gotten your Gizmo5 username and password entered correctly.

You also can use your Asterisk server to forward outbound SIP calls from your N95 to other phones. For example, if there are 10 close friends that you call frequently, assign each of them a SIP URI on your Asterisk server. We covered the setup process in this article. In a nutshell, create an Incoming Route in FreePBX named tom and point it to the phone number you wish to call. For destination phones outside your PBX, first create a Miscellaneous Destination called Tom-home that includes the home phone number. Then use this destination in your Incoming Route for tom. Save your entry and reload your FreePBX dialplan. Finally get your own fully-qualified domain name from a service such as dyndns.org. Assuming your FQDN was pbx.dyndns.org, then your Internet telephone entry for Tom in your N95 contacts would be this SIP URI: tom@pbx.dyndns.org. Otherwise, you'll need a SIP URI with the IP address of your Asterisk server, e.g. tom@36.24.36.1.

Adding a Free DID for Inbound Calling to Your Nokia N95. One of the world's best kept secrets continues to be the availability of free DIDs from ipkall.com in Seattle. This saves you $35 a year over the current Gizmo5 DID rate, and IPkall will give you a free phone number in one of several available area codes to use with the SIP device of your choice. Your Nokia N95 qualifies! Just be sure to place at least one call a month to the number, or it's automatically recycled to someone else. To register for a free IPkall account, go to this link and sign up. Your SIP Phone Number is your 11-digit Gizmo5 phone number starting with a 1. Your SIP Proxy for Gizmo5 is proxy01.sipphone.com. Now plug in a valid email address and create a password for your account. Your new phone number will be delivered to this email address. Once it arrives, you should be able to dial the number from any phone, and your Nokia N95 should start ringing. Answer the call just as you would any other cellphone call. The only difference is that you can talk as long as you like... for free. For other free DIDs and some great tips including ATA setup, go here.

Using Asterisk to Add the Missing Pieces. There are a number of ways you can use Asterisk to enhance your SIM-free Nokia experience. By enabling DISA, you can place a SIP call to your Asterisk server, obtain dial tone, and call anywhere using your existing Asterisk trunks. Here's the way we set this up. Edit /etc/asterisk/extensions_custom.conf and add a [custom-disa] context at the end of the file that looks like the following code. Be sure to set a VERY secure password in line s,7 by replacing 1234. It's your phone bill! Then set your IPkall DID number as the CallerID in s,13. By changing 701 in s,12 you can call any extension on your Asterisk server just by dialing 0 when you're using DISA. For our foreign friends, be sure to adjust the dial string length (10) in s,9 to meet your local needs.

Next, add an Incoming Route using FreePBX. For the DID Number, use a SIP name that is not easily guessed, e.g. DISA2375. This gives you an extra layer of password protection since anyone can try to guess your SIP URI's once they know the IP address of your Asterisk server. Leave all of the other entries at their defaults and, for the Destination, choose Custom Route: custom-disa,s,1. Save your settings and reload your dialplan. Ignore the warning that you're doing something odd. We know what we're doing.

Finally, on your Nokia N95, add a new Contact called DISA with an Internet telephone number to match the name of your incoming route above with the fully-qualified domain name of your Asterisk server, e.g. DISA2375@pbx.dyndns.org. Now you're ready to dial away by simply selecting this contact on your N95. Enter your DISA password when prompted and then enter a 10-digit phone number to call.

The WiFi HotSpot Two-Step (and a few more steps). Now that everything is working swimmingly, we're ready to take your Nokia N95 on the road. Here's the failsafe step-by-step to get connected in a WiFi HotSpot of your choice.

• Turn off the phone
• Arrive at HotSpot
• Turn on the phone
• Menu, Tools, WLAN Wiz., Pick Your HotSpot, and Start Web Browsing, Create WLAN While OffLine=Yes
• Using Browser, log into the HotSpot with your account name and password
• Leave the browser open so it'll be easy to log out when you're finished
• Menu, Tools, Internet Tel., Pick Your HotSpot AP
• Once Connected, Dial Away As Usual
• When finished, Hold Down Menu Button and Choose Browser App, Log Out of the HotSpot
• Turn off the phone

Cellphone Options. But what if you really do want to use the Nokia N95 in all its glory with the 5 megapixel camera and the multimedia goodies and even a cellphone provider? Well, it works great for just about anything you need. In fact, you can even take the SIM chip from your iPhone (even a First Generation iPhone) and plug it in. Phone calls work, voicemail works (even though you get two text messages when a new voicemail arrives... which is a lot better than Cingular in the old days when you typically got zero), and email and web browsing work great, too. Just select MediaNet as the access point when you open your Internet connection, and you'll be off to the races. Of course, all the cheapo, pay-as-you-go SIM cards work as well. Both Oxygen and Airvoice packages including free minutes and a SIM card are available at this eBay store for under $10. And there are lots of other options as well. Enjoy!
