SIP trunk - Q.850 reason codes
 
Dear All,

I have a problem with SIP trunk and reason codes (Q.850). I have two SIP trunks on CM5.2.1 via two SMs. First one is from PSTN and second one is to Cisco (Jabber clients).

I am able to call from PSTN to Jabber extension without problem. As well I am able to call from Jabber to PSTN. It looks good. My problem start when Jabber extension is unregistered or doesn't exist or so on. Customer want to differentiate these calls.

Scenario:
I call from mobile phone to ext on Jabber. Call go from PSTN via SM1 (SIP trunk 141 "PSTN-CM") -> CM 5.2.1 -> SM2 (SIP trunk 116 "CM-CISCO") to Jabber.
Jabber send me back to SM2 SIP/2.0 404 Not Found with reason Reason: Q.850;cause=27. It is correct. SM2 forwards it via SIP trunk 116 to CM.
Then CM sends SIP/2.0 404 to SM1 via trunk 141, but without any reason message.

Trace from SM2 to CM (communication SM1 -> Clan):

Do you have some idea why CM doesn't forward this reason code? Do I have to set some special value on CM for this Q.850 reasons codes?

Thank you very much for your help.

Best Regards

Radek
