Hi !
Asterisk sends a RELASE COMPLETE with cause code 34. It seems that
Nortel expects a RELEASE message in this state. The conversion
is done in the protocol engine of the MSDL.
Why would you want the cause code 34 to be sent ? Do you need a
special rerouting on the Nortel side ?
Yes. 34 is required by the Nortel to send the call to an alternative
destination.
Would it be a help if you send a cause 3 ? (RELASE msg)
No, I have already tried with PRI_CAUSE=3: Nortel just playes a tone instead of
rerouting. It seems to be a DISCONNECT, not RELEASE:

Hi!
My asterisk (1.0.7) is connected to a Nortel pbx with Digium E100P
card, both side are ETSI EuroISDN. I would like to reject an incomming
call with cause code 34, but the Nortel PBX gets the value of 31
instead of 34. It seems to work on the asterisk side:
< Protocol Discriminator: Q.931 (8) len=41

< Message type: SETUP (5)

My macro looks like:
exten => s,1,SetVar(PRI_CAUSE=34)
exten => s,2,Hangup
According to the debug on Nortel it gets 31 cause code in the release
complete q.931 message. Do you have any idea?
Thanks,
Miklos
