I posted this in the utm forum too, but maybe you guys can point me in the right direction.
----
PBX ip (freepbx but called wazo in the pic above) = 10.10.1.76 (internal lan)
ATA (obi200) = 10.1.3.102 (vlan 3)
The ata is configured on its own vlan to isolate it from the main lan. The ata is able to connect to external sip provider (on the internet) without any signaling or media issues.
PBX is configured on the local network and it too works well with its configured trunks and local lan clients.
Goal: An extension on the pbx has been configured exclusively for the ATA's use. Firewall rule below has been set up to allow the ATA to register successfully to the PBX.
Problem: That's as far as I get. The signaling sets up correctly but RTP/media is only getting passed inbound. That is, when a call is made using the extension configured above, I can hear the other party, but they can't hear me. Firewall has been disabled in freepbx to rule that out.
I'm not seeing anything in the firewall log or IPS. Ideas? Thanks!
