Hello,
I'm using sofia-sip-1.12.11 and i'm having o problem when i need to send an
ACK with a SDP and this message is bigger than 1400
bytes. The usual behavior would be to try sending the message by TCP (but
the calle does not accept TCP, only UDP), and if the
connection is not established, send it by UDP anyway. But, when sofia tries
with TCP and the connection is not established, it does
not send by UDP.
Here is the log where the error occurs:
nua: nua_stack_set_params: entering

tport_tsend(0x814cc10) tpn = */10.10.35.11:5060

Just making it clear, i do not want the ACK sent by TCP, i want it sent by
UDP. Other messages bigger than ~1,4k are sent by UDP, just the ACK
seems to have this problem.
If someone could help me i would be grateful.
