No audio when using Cisco IP Phone 7942 with Freeswitch
I have a Freeswitch installation with various models of IP phones, all models work fine except the 7942 model that when call is placed through to from other models, there will be no audio. However, if the 7942 initiates call to any other model the audio is fine in both directions. The network is not behind NAT as other devices work fine on the network, what could be the problem,? -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/No-audio-when-using-Cisco-IP-P...

Can you check what codecs are being negotiated on a good and a bad call.

The codecs in use in both cases is G711 ulaw, traffic capture using wireshark reveals that there was no rtp port negotiations, the reason for no audio, but if the 7942 initiates call port negotiation is done and audio is good. On Dec 17, 2015 11:09 PM, Moishe Grunstein <max@nysolutions.com> wrote:

This description doesn’t make any sense, can you paste the actual sip trace?

This captures made for differenc calls. Could you please send raw wireshark pcap file.
