So that suggests audio is flowing as follows in a unidirectional manner

Somewhere near the end this pops up which is slightly different, I am guessing 74.204.4.5 is your asterisk box

I am not sure why this is happening or if its still part of the same conversation
Overall it looks a bit like the asterisk box thinks it needs to send rtp to a different location than perhaps its meant to i.e. its asymmetric - you can check the sdp in the sip invite to see where media is expected to be sent to
There is no rtp coming back from 209.216.2.203 so possibly this is device that isn't meant to be part of the conversation and either doesn't exist or is not expecting anything and thus not responding
What are the addresses of the devices in this conversation? so that you can match the traffic to device

>> Thank you I have also tried those settings. The main thing is coming from my voip provider all I am doing is bridging the calls to two other devices (1 trixbox and 1 digium aa50) via IAX trunks. Both devices are answering with an IVR and when I call in I can not hear the IVR. However if I call directly to a SIP client the person answering the SIP phone can hear me but I can not hear them at all. Its definately not a NAT issue which is what makes it even more confusing. When the call is in place a sip show channels shows me both lefs of the call and they are both using either alaw or ulaw so it should not be a codec translation issue either.
