Configuring Linphone
IMPORTANT NOTE: If used over 3G/4G/EDGE, depending on your carrier and service plan, you may be billed for your data usage.

We recommend that you read each step through in its entirety before performing the action(s) 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 then select the Use SIP Account option.



If this is not your first time running Linphone, please bring up the menu (represented as 4 horizontal bars near the top left corner of the application) and select Assistant.

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:

UsernameThis is either the default extension 1777MYCCID OR 1777MYCCIDEXT, 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.
PasswordEnter 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.

Once completed, 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. For basic, trouble-free operation of the Linphone Softphone we recommend the following options; however you are free to change these settings as/if needed. With that said, please keep in mind that these settings may affect your stable use of the Linphone Softphone with your Callcentric account.



From here, disable all audio codecs except for the codec PCMU/8000 Hz, as detailed in the screenshot below:



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).
