Running a new environment with CM 4.2(3) and gateway configured as h323.
Inbound calls are working fine both ways and under show voice call stat i see the call is using g729r8
Outbound calls are connecting but no sound. on the phone i can see that it is transmitting RTP not receiving any from gateway. in the gateway i see the call is using g711.
Any reasons why inbound and outbound calls are using different codecs?
I tried to change the codec for inbound calls by placing codec g711ulaw under my voip dial-peer but then I got the same issue with outbound calls could no RTP packets being received from gateway.
dial-peer voice 10 voip
session ipv4: 188.8.131.52
