Hi Chen-Che,
Why does the BYE from callee fails and where ? Is it correctly sent to
outbound proxy? does the outbound proxy sends the BYE to proxy server
(with on Route hdr) ? does the BYE come back to outbound proxy ?
A more important question - does the proxy server do proxy or acts as a
B2B ?

Hi all,
I'm facing a problem as follows. The scenario is below.
Proxy server
Outbound proxy
caller callee
The packet flow from caller to callee is ``caller->outbound proxy->proxy
server->outbound proxy->callee''.
The outbound proxy invokes topology_hiding() and match_dialog() to prevent
the call from knowing the
IP address of the proxy server and enable successful packet forwarding. In
this scenario, the proxy server
must call record_route() when receiving an INVITE message.
Otherwise, the BYE message from the caller will not go under loose_route()
and thus the corresponding
dialog will not be terminated.
With record_route(), the BYE message from caller can be handled properly by
the proxy server. However,
my issues is that *the BYE message from callee* (no route field in the
header) cannot be handled
successfully so that the proxy server does not terminate the corresponding
dialog (as I wish).
Please kindly help to solve this problem. Many thanks in advance.
Best regards,
Chen-Che
