Linphone is an open source VoIP softphone available for most of the major desktop operating systems and mobile platforms. This simple to use and configure softphone allows for easy install and use with your Callcentric account.
This guide is based on version 1.1.6 for the Android platform but can easily be used for the iPhone version.
If used over 3G/4G/EDGE then depending on carrier and service plan used, you may be billed for your data usage.
Configuring Linphone for use with Callcentric is pretty straightforward and can be completed in a relatively short time.
We recommend that you read each step through in its entirety before performing the action indicated in the step.
Step 1
Launching Linphone
After installing Linphone please launch the softphone from your applications menu.
If this is your first time launching Linphone please view the welcome message and click continue.
If this is not your first time running Linphone please bring up the menu and click on Settings.
Step 2
Configuring your Callcentric account
We will now create a profile and enter the required credentials, such as your Callcentric number, password and SIP server:
Username:
This is either the default extension 1777MYCCIDOR1777MYCCIDEXT, where 1777MYCCID is the 1777 number assigned to you by Callcentric and EXT is the three digit extension you are trying to register this UA to.
For example: 17770001234101 would register to extension 101 on account 17770001234.
You cannot register to your account using only the extension number.
Password:
Enter your extension SIP Password here. Your extension SIP password is the password you created for the extension you are trying to use. You may edit the SIP password you wish to use in by logging into your My Callcentric account and clicking on the Extension menu link and then modifying the appropriate extension.
Domain:
sip.callcentric.net
Proxy:
sip.callcentric.net
Outbound
proxy: Enabled
The configuration screen should look similar to the one shown in the picture below:
Step 3
Configuring extra settings
DO NOT follow this step if you are not experiencing any problems.
There are extra settings which may be edited by the user for various purposes. We would recommend the following options for general trouble free operation of the softphone. You are however free to change these settings. We do recommend that you keep in mind that these settings may affect you stable use of Linphone with your Callcentric account.
Preferences
Start at boot time: Enable or Disable depending on your needs Enable Video: Disabled Stun server: Leave blank
Audio
Codecs:
pcmu
pcma
Video
Initiate video calls: Disabled Share my camera: Disabled
With the above settings you should have trouble free operation of LinPhone with your Callcentric account.
Step 4
That's it! You can now make a phone call.
You can make a test call to 17771234567, or if you are signed up for one of Callcentric's rate plans you
can place a call to a traditional landline or mobile phone by dialing either: 1 + the area code and number for calls to the US Or 011 + the country code, area code, and number for calls worldwide
(you may also use 00 instead of 011).
