Thanks for your quick reply,
I have the following routes:
For the invites
route[6] {
# -----------------------------------------------------------------
# Exchange 2007 Handler
# -----------------------------------------------------------------
xlog("L_INFO","Step 600 Entering ==== Route 6 (Exchange 2007) ======");
force_send_socket(10.10.2.24:5060); # for sending requets on eth1
if (t_relay("tcp:10.10.2.13:5060")){
xlog("L_INFO", "Step 601: Forward to UM2007 succecssful - From=$fu
To=$tu\n");
}else{
xlog("L_INFO", "Step 602: Forward to UM2007 not successful -
From=$fu To=$tu\n");
};
}
For the failure route
failure_route[1] {
xlog("L_INFO","Step 700 Entering ==== Failure Route 1 ======");
xlog("L_INFO","Step 701:Method [$rm]");
if (method=="INVITE"){
get_redirects("*");
force_send_socket(10.10.2.24:5060); # for sending requets on eth1
if (t_relay()){
xlog("L_INFO","Step 702: t_relay ok");
}
}
}
As UM requests a different port (5065) in the 302 message, I cannot use
t_relay with TCP in the failure_route. With t_relay I have to submit the
whole address like
t_relay(tcp: dest_ip:port) and I cannot always predict the port in this
case.
Best regards
Peter
