I am having some issues with a FreePBX system dropping calls consistently at 32 seconds. I’m running FreePBX 126.96.36.199 with Asterisk 16.11.1.
I’ve seen a lot of other posts with similar issues as mine and it usually comes out to be a NAT issue, but I can’t figure out where my issue is. I am forwarding UDP port 5060 (pjsip not chan_sip) and RTP ports 10000-20000 to the internal IP of the PBX and have firewall rules block it if the IP address isn’t coming from the Twilio IPs I am using for my trunk. If i go to asterisk SIP settings and detect network settings it fills in the external IP with the correct IP. I have all of my internal networks added under asterisk SIP Settings as well. Here are logs for a call that dropped: https://pastebin.com/uM5955cd
