Problem with one way audio on 5300 gateways.

I can ping from site A(5300) to B(5300) and B to A but when a voice call is made site A hears it ringing and site B picks up and says hello and site A can hear that but when site A says hello site B does not hear that.

Re: Problem with one way audio on 5300 gateways.

1. Check if you have no ip routing in the router config. If

yes enable ip routing

2. check the codec negotiated by both side. Could be a codec miss- match in one direction.

3. turn on debug and see what address was sent int the h225 message

for rtp stream connection .
