Hi,

Is the provider leg SIP/Digital (PRI T1/E1)/FXO?

You will need to run additional debugs along with debug ccsip messages:

debug voice ccapi inout.

debug isdn q931 (if DIGITAL)

debug vpm signal and debug vtsp all (if FXO)

refer to Voice call troubleshooting:

do not run on terminal if ISR in production.

Regards,

Adarsh Chauhan

Please mark Correct or helpful

The problem is fixed.

The wrong ip interface was attached to the outgoing dial-peer which points to the ISP.

voice-class sip bind control source-interface GigabitEthernet0/0/0.1
voice-class sip bind media source-interface GigabitEthernet0/0/0.1

This was simply recovered by verifing :

CUBE#sh ip cef XX.XX.XX.XX

0.0.0.0/0

nexthop XX.XX.XX.XX GigabitEthernet0/0/0.1
