Hi Huong,

Thanks for your response. the call flow is :   (Originate Gateway) SIP ----> SIP( Terminate Gateway )-----> PSTN---> Mobile phone.

Here is my dial-peer config:

dial-peer voice 123998 voip

description Inbound Peer Aicent

translation-profile incoming 250

max-conn 60

voice-class codec 1

session protocol sipv2

incoming called-number 250.

It's correct behaviour. 31 cause code is mapped to 404 sip code by default. Please check this link for more information:

http://www.cisco.com/en/US/docs/ios/12_2t/12_2t11/feature/guide/ftmap.html#wp1022663

You have options to change this default mapping. It's desribed in that document as well. For example:

sip-ua 

 set sip-status 486 pstn-cause 34

 set pstn-cause 17 sip-status 503

I guess in your case it has to be

set pstn-cause 31 sip-status  

I guess it can be 480.
