Getting Started with Incredible PBX for Elastix 2.5 (Cloud Edition)

Here’s a quick overview of the installation and setup process for Incredible PBX for Elastix 2.5 @ RentPBX.com:

  1. Sign Up for Incredible PBX for Elastix 2.5 in the Cloud
  2. Complete the Install of Incredible PBX with two automatic reboots
  3. Set Up Passwords for Incredible PBX
  4. Configure Trunks with Incredible PBX
  5. Connect a Softphone to Incredible PBX
  6. Configure SMTP Mail for Incredible PBX

1. Sign Up for Incredible PBX for Elastix 2.5 in the Cloud at RentPBX.com

Visit RentPBX.com and choose the Elastix build option. Then complete the following steps:

Step #1. Select a location for your cloud-based server.

Step #2. Choose Elastix 2.5 IncrediblePBX Ready option.

Step #3. Specify a hostname for your server.

Step #4. When you begin the payment/checkout phase, enter your coupon code to take advantage of the $15/month discounted rate: NOGOTCHAS. Wait for the confirmation email with your server credentials and dedicated IP address.

2. Complete the Install of Incredible PBX

Nothing tricky here. It’s a 10-minute automated setup. Log into port 20022 of your server as root with your default password using SSH or Putty. Once you’re logged in, RentPBX will go through two setup cycles to complete the install and randomize all of your passwords for Incredible PBX. The first pass addresses some security vulnerabilities in the Elastix 2.5 base install and then prompts for the MySQL root password which must be passw0rd (with a zero). Next, you’re prompted to set up an admin password for the GUI. Make it secure! Then your server will reboot. After 60 seconds, log back in to port 20022 as root with your default password again. Type y to install Incredible PBX. Incredible PBX will first apply the latest upgrades for CentOS and Elastix. Be patient. The list is a long one. After the second reboot, log back into your server on port 20022 as root one final time and let Incredible PBX complete the install and secure your server. You’ll need to enter your MySQL and GUI passwords once again. Be sure to use passw0rd for MySQL! After the third reboot, log back into your server on the standard port 22 as root. Allow Incredible PBX to run its Automatic Update Utility to bring your system current. That’s it. You now have a secure, turnkey Elastix® PBX that’s ready for use.

3. Initial Configuration of Incredible PBX for Elastix 2.5

Incredible PBX is installed with the preconfigured IPtables Linux firewall already in place. It implements WhiteList Security to limit server access to your server’s IP address, your desktop computer’s IP address, and a few of our favorite SIP providers. You can add additional entries to this WhiteList whenever you like using the add-ip and add-fqdn tools in /root. There’s also an Apache security layer for web applications. And, of course, Elastix 2.5 has its own security methodology. RentPBX randomized extension and DISA passwords as part of the initial setup process. Out of the starting gate, you won’t find a more secure VoIP server implementation anywhere. After all, it’s your phone bill.

Even with all of these layers of security, here are 5 Quick Steps to better safeguard your server. You only do this once, but failing to do it may lead to security issues you don’t want to have to deal with down the road. So DO IT NOW!

Log into your server as root with your root password and do the following:

Make your root password very secure: passwd
Set your correct time zone: ./timezone-setup
Create admin password for web apps: htpasswd -b /etc/pbx/wwwpasswd admin newpassword
Make a copy of your other passwords: cat passwords.FAQ
Decipher IP address and other info about your server: status

Using a browser, you’re not ready to log into the Elastix 2.5 GUI with your new admin password.

4. Activate Trunks with Incredible PBX for Elastix 2.5

For those migrating from another aggregation including PBX in a Flash, this should be familiar territory for you. Using a browser, log into Elastix 2.5 at the IP address of your server. Before you can actually make or receive calls outside your PBX, you’ll need at least one trunk. In the Elastix 2.5 GUI, click PBX -> Trunks. Once you have your credentials from a provider, choose a provider from the list of preconfigured trunks on the right or create a new one. If you’re using one of the preconfigured options, remember to enable the trunk after adding your desired CallerID and credentials. Then save your settings and reload your Asterisk dialplan. That’s it. You’re ready to go.

5. Configure a Softphone with Incredible PBX for Elastix 2.5

Incredible PBX comes preconfigured with two extensions (701 and 702) that let you connect phones to your PBX. You can connect virtually any kind of telephone to your Elastix 2.5 PBX. Plain Old Phones require an analog telephone adapter (ATA) which can be a separate board in your computer from a company such as Digium. Or it can be a standalone SIP device such as ObiHai’s OBi100 or OBi110 (if you have a phone line from Ma Bell to hook up as well). SIP phones can be connected directly so long as they have an IP address. These could be hardware devices or software devices such as the YateClient softphone. We’ll start with a free one today so you can begin making calls. You can find dozens of recommendations for hardware-based SIP phones both on Nerd Vittles and the PIAF Forum when you’re ready to get serious about VoIP.

We recommend YateClient which is free. Download it from here. Run YateClient once you’ve installed it and enter the credentials for the 701 extension on Incredible PBX. You’ll need the IP address of your server plus your extension 701 password. You can find them in /root/passwords.FAQ. Fill in the blanks using the IP address of your server, 701 for your account name, and whatever password is assigned to the extension. Here’s what your entries should look like. Click OK to save your entries.

Once you are registered to extension 701, close the Account window. Then click on YATE’s Telephony Tab and place some test calls to the numerous apps that are preconfigured on Incredible PBX. Here are a few numbers to get you started:


123 - Reminders
947 - Weather by ZIP Code
951 - Yahoo News
222 - ODBC Lookup (try: 12345)
DEMO - Allison's IVR Demo
TODAY - Today in History

6. Configuring SMTP Mail with Incredible PBX for Elastix 2.5

Outbound email support using Postfix is preconfigured with Elastix 2.5. You can test whether it’s actually working by issuing the following command using your destination email address after logging in as root:

echo "test" | mail -s testmessage yourname@gmail.com

If you don’t receive the email message within a minute or two and you’ve checked your spam folder, chances are your ISP is blocking downstream SMTP servers in an effort to combat spam. Comcast is one of the usual suspects. To enable outbound email service for delivery of voicemail and other email messages with a provider blocking downstream SMTP servers, you first need to obtain the SMTP domain of your ISP, e.g. smtp.comcrap.net. Next, edit /etc/postfix/main.cf and add your SmartHost entry [in brackets] to the line that begins like this: relayhost =. The line should look like this: relayhost = [smtp.comcrap.net]. Save your addition and restart Postfix: service postfix restart. Be sure to try another email test message after completing the SmartHost update. To use Gmail as your mail relay, see this tutorial.

Configuring Google Voice

We have included the Python implementation of gvoice in /root for those that want to experiment by making calls and sending SMS blasts the "old-fashioned" way. While Elastix does not directly support native Asterisk 11 Google Voice functionality, you now can use a SIP gateway to access Google Voice and make free calls in the U.S. and Canada.
