[asterisk-users] Handling SIP error codes/ISDN codes

[das sandesh]

Hi,

I was trying to use 2 of asterisk servers and interconnected, one of them as
a peer to other sever (configured in sip.conf), so all the calls to server 1
will just be passed to server 2 (has PRI Card, TE 412P, only one PRI
connected), i was sending calls to server 1 and that would send to server 2
and then dial out using Dahdi, but the problem that i got was the hangup
cause codes, i was not able to pass the appropriate ones to the server 0
(Test server) that sent a call to server 1. For example, when the user at
server 0 (test server) made a call to server 1, that sends it to server 2
and connects to the appropriate destination, but in the mean while if we
just cancel the call, we need to see the SIP error code as 487 - Request
terminated, but I was only able to see the ISDN core in PRI debug on server
2, but was not able to see '487' in sip debug, even though if i am handling
the error code conditions........Is there any way of handling the error
codes properly....?

Asterisk version: 1.4.22.1
Libpri: 1.4.10.1
dahdi: 2.2.0.2 are the versions that I am using.


The way I was handling the codes for the server 2:
