<DIV>Seems like you have done your research and what you write seems
reasonable. It's difficult to give you an answer without having a complete
ngrep trace. However, you should also look at the Record-Route and Route
headers...</DIV>

TCP... Problem</DIV>
<DIV><BR></DIV>
<DIV><FONT face=Arial size=2><SPAN class=395273916-14022006>Hi
everybody,</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN
class=395273916-14022006></SPAN></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=395273916-14022006>I have a UDP2TCP
problem with Ser. (0.9-4)</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=395273916-14022006>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.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=395273916-14022006>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.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=395273916-14022006>If I Check the
message for an Ack or a BYE sent to the TCP GW the uri is correct
:</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=395273916-14022006>the
transport=tcp is added. </SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=395273916-14022006> <FONT
size=2>Request-Line: ACK sip:50033299848400@200.1xx.xx.xx:5060;transport=tcp
SIP/2.0</FONT></SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=395273916-14022006>I have red that
this is sufficient to let SER understand that it must be sent via
TCP.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=395273916-14022006>unfortunately,
this message is ent thru UDP. </SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=395273916-14022006>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...</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=395273916-14022006>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.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=395273916-14022006>I wondering it
was because the Carrier Gw didn't receive an ACK TCP from my
server..</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN
class=395273916-14022006></SPAN></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=395273916-14022006>Well I'm
completely lost... as you can feel with my message...</SPAN></FONT></DIV>
