[Serusers] SER/PSTN Gateway conf

[Kostas Marneris]

Hello,
The call signalling exchange is a good start but it's not enough.

What some people here asked you is a capture of the SIP BYE mesg
which GW sends to SER.

something like that, for example :

BYE sip:user1 at 1.2.3.4:5060 SIP/2.0
Via: SIP/2.0/UDP 5.6.7.8:5060;branch=z9hG4bK3E01596
From: <sip:1234567890 at 5.6.7.8>;tag=12FB3150-15EC
To: <sip:12341234567890 at mydomain.com>;tag=sei-6416
Date: Tue, 15 May 2007 11:42:43 GMT
Call-ID: 3A6DE4DC-21011DC-998FA089-7CE33D49 at 5.6.7.8
User-Agent: Cisco-SIPGateway/IOS-12.x
Max-Forwards: 70
Route: <sip:3.3.3.3;ftag=12FB3150-15EC;lr=on>
Timestamp: 1179229379
CSeq: 102 BYE
Reason: Q.850;cause=16
Content-Length: 0


1.2.3.4	: SIP Phone
5.6.7.8	: GW
3.3.3.3	: SER

1234567890	: PSTN number of the caller (@ PSTN side)
12341234567890	: PSTN number of the callee (@ IP side)


Try to find a way (ngrep/tcpdump) to capture this mesg
or all mesgs for this session .
