weird CUBE behavior

Hi Everyone,

I got a strange behavior and I don't know if it is configuration related;

I have a cisco UBE as a WAN edge performing NAT and SBC. Behind this UBE I have an Asterisk for VM and a CUCM. Interaction between these 3 works no problem.

I'm trying to setup voice register for a friend with a ATA at the end of a GRE Tunnel. After having issues I've try to reproduce it using x-lite - same behavior.

Here is what happen. ITSP forward calls to my UBE using DID@IP.address SIP URI. If the DID is a ephone or a dial-peer, no problem - the call completes.

If the DID is a SIP voice register DN here is what happen. If the ATA/Softphone is not registered I have a loopback dialpeer for the DID to be routed to VM - and it works. If the user is registered, the call gets hairpined to the PSTN.

The debug dialpeer shows 2 potential dialpeer (the SIP user and the PSTN trunk) Not a single SIP message gets sent to the SIP user and the call starts looping.

Calls from SCCP to SIP extensions and vice versa works

Any idea where I should start? What do you need to see from my config?

OK, done further troubleshooting.

The right dialpeer is selected when debugging voice ccapi inout

CME is sending to the ITSP SIP 488 Media not acceptable.

I've tried hardcoding everying to g711ulaw and still the same issue.

Any hint?
