SIP User-to-User field to ISUP sig.UserToUserInformation
« on: July 30, 2014, 04:45:38 AM »
Hello

I will need to pass User-to-User data from SIP-T to SS7 network in both directions.
Is there a way to do it ?
I have INVITE from SIP-T to Yate with:

INVITE sip:123456789@192.168.1.2 SIP/2.0
User-to-User: 12345678999

But how to place it in regexroute dialplan ? Is there some sip variable that contain this value ?

I have tried tu put constant value like:

.*=sig/${called}.;link=link-1;sig.UserToUserInformation=12345

But there wasn't any trap of it in sigdump file.

Hello

OK, now I know that sip headers are in ${sip_lowcase-name}, so I have ${sip_user-to-user} in from SIP to SS7,
and something like this:

.*=sig/${called}.;link=link-1;sig.UserToUserInformation=${sip_user-to-user}

How to get from SS7 do SIP this value ?

osip_user-to-user=${isup.UserToUserInformation} ?

Greetings
