Hi there,
I'm having a problem when I try to send a large INVITE with Sofia. When the
stack detects that my INVITE exceeds the MTU and the default transport is
UDP, it correctly tries to send it via TCP. However, if the TCP connection
fails, when sofia tries to fall back to UDP again the INVITE does not get
sent to the network. I've captured a log:

After the "nta: INVITE (110482403) TCP refused, trying UDP" message nothing
happens until the timers start firing. Shouldn't the UDP INVITE be sent
immediately after sofia verifies that TCP has failed? Is it waiting on a
timer of some sort? Am I missing something here?
This is with Sofia-SIP 1.12.10.
Thanks in advance.
Fabio
