[OpenSER-Devel] sipp 2.0, VIA sent-by and transaction matching

[Henning Westerholt]

Hi,

i use sipp as part of the test suite for the server. After a recent system upgrade
(which upgraded also the sipp) i noticed that many tests stopped working.

The sipp (2.0.1-TLS-PCAP, version 20070516, built May 18 2007, 11:25:38.)
uses now the 'sent-by' parameter for building VIAs. This seems to break the
transaction matching (test 20.sh for example don't work anymore).

An example message (ngrep -W byline) looks like this:

U 127.0.0.1:5060 -> 127.0.0.1:5059
SIP/2.0 180 Ringing.
Via: SIP/2.0/UDP 127.0.0.1:5059;branch=z9hG4bK4783.c7afa14., SIP/2.0/UDP 127.0.0.1:5061;branch=z9hG4bK-3206-1-0.
From: sipp <sip:sipp at 127.0.0.1:5061>;tag=3206SIPpTag001.
To: sut <sip:foo at 127.0.0.1:5059>;tag=3200SIPpTag011.
Call-ID: 1-3206 at 127.0.0.1.
CSeq: 1 INVITE.
Contact: <sip:localhost:5060;transport=UDP>.
Content-Length: 0.


Is this behaviour normal, e.g. are the messages of sipp invalid? Or is there
an error in the transaction matching logic of the server?

Cheers,

Henning
