Ive gone over the forum for hours trying to figure this out, with tons of google searches. All seem to point me to a NAT / Firewall issue. But my settings their have not changed that I know of.
Everything was working a few days ago, then today it started on all inbound routes except for the primary. Now all the inbound routes have the same issue. When we receive an inbound call, we hear the caller and they can’t hear us. There is no issue with outbound, audio works both ways.
NAT is enabled, external and internal IP address our correct in the Asterisk Sip Settings.
Nothing has changed on the fire wall, SIP ALG disabled.
Have nat translation and port forwarding setup for 10000-20000.
Have reboot the freepbx / asterisk server, no change.
Any help would be greatly appreciated I am running FreePBX version FreePBX 220.127.116.11
If you need any other info from me please let me know.
Update, after setting all the inbound routes to ring groups, all work but one. It still has the same issue, no ringing from the caller inbound to freepbx, and once we answer the call we can hear the caller they can’t hear us. But 2 way audio on the other inbound routes, also they all run off the same Flowroute trunk.
