I am configuring a E1 PRI in Australia connected to a 3935 GW which has a SIP trunk to a 8.6 Call Manager. The circuit is in and good with no errors and inbound calls from the PSTN work fine. However, outbound calls connect but there is no audio from the Call Manager to the PSTN however the call manager phones can hear the PSTN side, i.e.:
Cisco verified that the audio is making is way from the phone to the gateway correctly and says the issue is a carrier issue which of course Telstra disagrees with. I have pasted the santized gateway config below. Does anybody have any ideas?

This was a bug in IOS. Going from 15.2T to 15.1M resolved the issue. As I said, we (Cisco and me) verified IP routing, we verified that the actual voice media packet was getting to the gateway but there was just no voice. Finally I went from a 15.2T train to a 15.1M load and it worked like a champ.
