Hi,
Okay and if contact header is not being changed why proxy will send 481
response to BYE. One more question When Proxy can send 481 response to BYE?
I think it can send in B2BUA mode. Any other scenario for this?
Regards,
Vivek

Hi,
If proxy is not maintaining the session, it would treat BYE as any other
transaction and process it the same way as INVITE (treat it like any
other transaction).
IMO, updating the Request URI with 'Contact' header would work.
Thanks

Hi,
If proxy is maintaining call-leg then there should be
Record-Route
header in 180 and 200 response but as there is no Record route header
present which means proxy is not maintaining session and if UAC is
sending
BYE for that session to proxy which is not maintained by it, it can send
Call does not exist
Comments expected..

Vivek

Update the reqeust-uri, once the dialog is established, (based on the
contact header.)
