A2B: Setting up a trunk in A2Billing

USERNAME/PASSWORD BASED AUTHENTICATION

If we are using username/password authentication with our provider then we need to set our trunk up manually in Asterisk. We will give that trunk a name and then use that name, instead of the IP address, in the A2Billing trunk setup screen above.

Here’s an example of setting up a trunk with altotelecom.com. Many providers will be similar and provide the connection details you need to enter. These settings go in the file /etc/asterisk/sip.conf.

If you need to ‘register’ with your termination provider enter the register line under the existing [general] section –

And then enter the connection details below that. Here we are calling the trunk ‘altotelecom’. This will be used as the ‘IP Address’ in the A2Billing trunk set up page –

Next, apply those settings by running a ‘sip reload’ in Asterisk –

Now we can set up the trunk in A2Billing, using the name we specified above, instead of the IP address –
