Hi. I have just installed freepbx. I have updated all my modules and configured a SIP Trunk to my ISP. I can successfully make outside calls and calls between extensions. I can’t receive any calls via my ISP SIP Trunk. FreePBX status shows that one trunk is online and registered.
If I setup my SIP Phone with the ISP SIP details I can make and receive calls, but it does not work through the PBX.
Can somebody direct me where to start my troubleshooting
