[SR-Users] BUG? - Dialog module timeout BYE is not ok.

Hi,
Following this issue, and the issue "BYE dialog timeout bad syntax" from
Julia.
I have 2 kamailio servers. srv1 creates a dlg_timeout BYE and sends it to
srv2 that forwards the BYE to the next sip server (some other server...).
I can definitely see that the BYE that is being forward is malformed. The
TO header info is not complete (the port section for example).
When a "normal" bye is received from srv1 (not dlg_timeout) all works fine.
One thing that i do in this scenario, on srv2 i use uac_replace() on the TO
header. So, it is OK that the final destination is different (i do
translations).
I attached the BYE from both servers.
Any ideas?
Thanks,
Uri
You probably meant the To and From headers, I'm guessing. Yeah, as long as
there is no display name component, URIs in headers like that don't have to
go in <>s. The way Kamailio sends it is grammatically valid, per RFC 3261.
The user agents are at fault for not understanding it correctly. Alex
