Hi Alex,
First, about the Route hdr - opensips adds a Route hdr in BYE only if
the dialog (on that specific leg) received a 200 OK INVITE with RR
header - can you confirm this at (1) signalling level and (2) at dialog
level (do a dlg_list via MI).
Now, about the bogus BYE - indeed, it is strange - do you use a local
route for accessing the BYEs requests? Attached is a small debugging
patch - please apply it a nd see if you get any WARNINGs at runtime.
Regards,
Bogdan

Hi,
I have a strange behavior of OpenSIPS 1.6.2. First dialog module
_/sometimes/_ sends a wrong bye (generated by dialog module on timeout):
Here’s a correct one:
BYE sip:[email protected]:7640;transport=UDP SIP/2.0
Via: SIP/2.0/UDP 212.179.159.18;branch=z9hG4bKd6c7.7f7a3d36.0
To: <sip:[email protected]:5060>;tag=8548
From: <sip:[email protected]:5061>;tag=8547
CSeq: 2 BYE
Call-ID: [email protected]
Content-Length: 0
Max-Forwards: 70
And here’s a wrong one:
BYE sip:212.179.159.9:7640 SIP/2.0
Via: SIP/2.0/UDP 212.179.159.18;branch=z9hG4bKc6c7.7ecb1057.0
To: <sip:[email protected]:5060>;tag=8547
From: <sip:[email protected]:5061>;tag=8546
CSeq: 2 BYE
Call-ID: [email protected]
Route: <sip:[email protected]:7640;transport=UDP>
Content-Length: 0
Max-Forwards
In a wrong one there’s Route header inserted (by mistake?) and the
message is cut at Max-Forwards line. It’s missing “:70\r\n”.
Both of the BYEs above I got just by running test with SIPP. This can
happen even with single call, not related to stress. I.e. one call it
might send a correct BYE and another call a corrupted BYE, without any
reason, because calls are exactly the same.
Another issue is, looks like t_newtran() is unable to handle
retransmissions. In this test UAC and UAS are in the same machine
(.9), and you can’t see INVITE from OpenSIPS (.18) to UAS because it’s
fragmented.

This issue happens during stress test.
Any ideas, please? The OpenSIPS 1.6.2 is compiled with system malloc
and runs over VMware.
