We have got our trunk setup and now we need an extension so we can make a test call via the trunk. For testing I’m going to be using x-lite. A free sip softphone for Windows and Linux. You can download it free in here: Windows Linux
Adding an extension in FreePBX First we need to click on Applications and then click on “Submit” to add a “Generic Sip Device” Next we need to get a basic extension First enter a “User Extension” –100 Next enter a “Display Name” – I used the same as above but you could enter a real persons name or whatever you want.
Now see below, at device options and enter a secret. This is the password for the extension
Finally click on “Submit” and then we need to click on the orange “Apply Configuration Changes” for the extension to take effect
Configuring X-lite You can see it here We probably can’t the outside world just yet as we need an Outbound Route. That will be in the next article http://asteriskvoipsystem.org/setting-up-an-extension/
