2010 Bargain of the Year: Nortel 1535 Color SIP Videophone

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. :wink:

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.

  • 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!

    Would you please demo/explain how to setup a video call between this phone and Apple iChat

    .. since iChat uses SIP for video, too

    I cannot afford a MAC device merely to video chat with my family who all except for me use such.

    I would greatly prefer a hardware appliance for video chat and NOT software.

    If not the nortel 1535 can you recommend an inexpensive iChat video capable alternative sip phone?

    ((
    can the yealink T46G do video chat using inexpensive [skype capable] USB video cameras?
    ))

    I use skype capable as the feature benchmark but have zero interest whatsoever myself using skype as it’s not an open standard and skype-sip requires costly business licenses.

    ((
    can the cisco SPA 525G2 be “hacked” to use [skype capable] USB video cameras for video chat? or other hackery?
    ))

    [WM: Please head to the PIAF Forum. That’s what it’s for.
