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.<br>
