[Asterisk-Users] Hangupcause to handle Called party disconnect ? PSTN----E1----OldPBX---E1--Asterisk

[Marco Mouta]

Hi,

I've been debuging the call disconnection problem in our architecture:

PSTN---E1---OldPBX---E1---Asterisk

This is our problem:

-SIP user agent "A" calls a pstn phone "B".
-"B" hangs up the call.
-SIP user agent "A" starts listenning busytones... But the call still on.
(and being payed).
- Call only ends when it is correctly hanged up in the SIPphone.

I've been tracing the communications between the OldPBX (NETWORK) and
Asterisk (USER SIDE) and i found this:


M03 PROGRESS
I08 Cause

Private net-remote

This trace reports to a called party that hanged up the call, then our old
PBX talked to Asterisk with :

PROGRESS
Cause Code=16

and Asterisk answered with

Location=User
Cause Code=98

I've been looking ISDN cause Codes and i found:

Cause No. 98 - message not compatible with call state or message type
non-existent.
This cause indicates that the equipment sending this cause has received a
message such that the procedures do not indicate that this is a permissible
message to receive while in the call state, or a STATUS message was received
indicating an incompatible call state.

I hope you can advice me. Is it affordable to use Hangupcause?

what we need is that, if the called party hangs, asterisk should hang
(safety reasons on billing)..

exten => _2XXXXXXXX,1,Dial(Zap/g1/${EXTEN})
exten => _2XXXXXXXX,2,gotoif,$[${HANGUPCAUSE} = 16]?99999|1
exten => 99999,1,Hangup


I'm not sure if this is possible neither recommended, should be
HangupCAUSE=16 or =98 ??

Best regards,
Marco Mouta
