I am new to FreePBX and am trying to use it to handle a routing issue between a hosting provider and a SIP enabled Mass Notification System. In order to get myself going, I have installed FreePBX 18.104.22.168 on a VM and one my PC I have two soft phones registered as ext 3000 and ext 3002. The PC and FreePBX are on the same subnet. The Windows Firewall and FreePBX firewall are disabled.
I can place a call from either extension to the other successfully, but I get no audio in either direction.
I can call #43 from either extension and send and receive audio.
I have run wireshark on my PC and when using #43 see the call setup and subsequent RTP packets in both directions (of course). When I try to call from one extension to the other; however, I see the call setup, but no RTP stream.
I have tried enabling call recording to force audio to pass through FreePBX but still no RTP traffic.
I have limited the CODEC to ulaw, but have also tried with other CODECs enabled.
Any suggestions would be greatly appreciated.
