      I know it has to be a firewall or network setting. But tired Jared is tired and not thinking clearly.

      IAX2 trunk between client FreePBX 13 and my system (older FreePBX 11).

      I have routes setup and calls complete.

      Call from my PBX to Client and there is 2 way audio.

      Call from client to my PBX, and I can hear client, but they cannot hear me.

      Connection between phone systems is over an IPSEC VPN tunnel.

      Which side is the problem here?

      Both ends have an Ubiquiti ERL for their router.

        Would it be a port issue? I've not dealt with PBX systems like you, @art_of_shred, @Mike-Ralston or others have,.. but if the ports are open, I would think that should cover it.

          Is the MTU set correctly?

          Are you doing NAT over the VPN?

          Do you have STUN setup?

            Also did you add the network for the remote site in asterisk?

              Oh yeah, check subnet masks on the machines, just in case.

                Did more trouble shooting on this today and I am still confused.

                Both PBX systems were using the external IP addresses and not the IPSEC VPN.

                I did try it on the IPSEC VPN with no difference.

                PBX A calls PBX B and the person on PBX B has 2 way audio. The person on PBX A cannot hear the person on PBX B.

                PBX B calls to PBX A and both parties have 2 way audio normally.

                PBX B also has an IAX2 trunk to PBX C and PBX D. All calls work perfectly for those.

                  Here is a test call from PBX A (ext 220) to PBX B (ext 103) where PBX A cannot hear PBX B.

                    Circling back to this... I need more damned time in a day....

                    As far as I can tell the firewalls are all correctly forwarding traffic.

                    WTF

                      @Jason said in One way audio on an IAX2 trunk:

                      Also did you add the network for the remote site in asterisk?

                      Found this topic again after checking the IAX2 tag.

                      Thought I would update with the answer.

                      This was the problem
