Your SCCP ANN is a different thing than what you are troubleshooting.
The problem you are experiencing is probably because your voice path is not cut thru soon enough.. There are some steps you need to take to fix this.. First look at the PRI/CAS messages and when you see a call proceed. Then, check with debug mgcp packet if the gateway is signalling the CCM to do e MDCX. If it is, check the sccp messages and find out if you see the proceed.
The second link was useful. It turns out this seems to be a capabilities issue for MGCP gateways and QSig which are being used in this case.
We have requested an PI=8 from the PBX at the other end of the MGCP gateway. The PBX operators are changing their software code to try and provide this. We are told by Cisco TAC that this should provide the correct signalling back to the call manager, so that it can provide ringback tone.
If you have any further ideas, please to recommend.
