Hi
everybody,
I have a UDP2TCP
problem with Ser. (0.9-4)
The UACs connected
to my SER Proxy are all UDP. When I use some carriers to connect them to PSTN
The Carrier Proxy / GW could talk UDP or TCP. It depends on the
destination.
Each time the
Carrier GW want to talk TCP, the contact field is correct and contains the
'transport=tcp' mention. all seems to be correct and, after a complete reading
about this subject in the list, I trust that using t_relay() must do the right
translation and send response via TCP to the Carrier GW when this one is
transport=tcp declared.
If I Check the
message for an Ack or a BYE sent to the TCP GW the uri is correct
:
the transport=tcp is
added.
Request-Line: ACK sip:50033299848400@200.1xx.xx.xx:5060;transport=tcp
SIP/2.0
I have red that this
is sufficient to let SER understand that it must be sent via
TCP.
unfortunately, this
message is ent thru UDP.
May I force with a
t_relay_to_tcp ? As this case depends on the carrier dynamic routing it
could be complicated because of the need to know the destination to script
t_relay_to_tco(uri, port)... If anybody has the trick or any
advice...
Other thing related,
when TCP is the transport mode from the Carrier GW and I forward staefully to
the UAC (Asterisk) the call failed between Asterisk as UAC and the carrier
GW.
I wondering it was
because the Carrier Gw didn't receive an ACK TCP from my
server..
Well I'm completely
lost... as you can feel with my message...
I need Help.. But
don't cal me Harry ;)

Christian Thomas
