Can anybody advise me regarding configuring a trunk from FreePBX 17 to ASTPP using IP authentication, as my trunk doesn’t seem to be working no matter what I try. In my setup I am using FreePBX 17 to register extensions etc and ASTPP to handle billing of outgoing calls.
seem like you have to add a trusted peer ip to your FreePBX
I did do that.
You can review this guide on IP and SIP-based authentication: ASTPP Documentation. It covers the configuration and should be helpful for setting up a trunk from FreePBX 17 to ASTPP.
Let us know if you run into any specific issues while following the steps.
