not able to make outgoing calls ( SIP/2.0 503 Service Unavailable)

Hi All,

 

Im facing problems with my Cisco ISR, only outgoing calls are failing incoming calls are working fine.

 

Ive tried several things

 

- disabled early offer

-enable/disable MTP in sip trunk

remove keepalive options in dial-peer.

However no success

 

Please find below sip messages.

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
