Hi,
As i wrote, when the BYE is "normal" not generated form dlg_timeout. srv2
that forwards it, does it OK.
The TO/From headers in my scenario are the same as the initial request in
both servers (there are 2 legs for each call (incoming and outgoing), on
each leg i use the same initial headers.Ii hope i was more clear now.
Thanks,
Uri

IMO the timeout-triggered BYE should have identical
From/To headers as the
initial request - otherwise it may cause issues with clients that are
strict, or rely on identical headers (like in your setup).
regards
