Part 3 – Create a trunk in Elastix

This is part 3 of a series of posts on setting up an Elastix extension with A2Billing. See here for details of the other parts – Using A2Billing to account for extension calls in Elastix

Now we have got an extension set up we need to be able to make calls to the regular telephone system. To do this we need an account with an ITSP, I’m going to use callwithus.

First click on Trunks and then Add SIP Trunk -

Next scroll down and give your trunk a name, then enter your trunk details. I’ve pasted mine but this will vary by provider. If in doubt as to what details to use you should contact your provider -

Click Submit and then apply your changes -

That’s the trunk setup. Go to the next part to create an Outbound Route – Part 4 – Create an outbound route in Elastix
