Well, i read the documentation again, and found t_lookup_request, and
t_check_trans.
Question 1 - t_lookup_request() creates the transaction if it doesn't exist,
correct? However, t_check_trans only checks to see if the transaction already
exists, correct?
Question 2 - Assuming that t_check_trans only checks to see if the transaction
already exists, then is the following correct?
Currently I do the following (after stripping out a bunch of stuff)
if (!t_relay()) {
if (!is_method("ACK")) {
sl_reply_error();
}
}
should this, instead, actually look like the following?
if (is_method("INVITE")) {
if (if !t_check_tran()) {
t_relay();
}
} else if (!is_method("ACK")) {
sl_reply_error();
}

If the message is completely identical then it is a retransmission.
Retransmissions should be detected by tm module (e.g. t_relay()) and
absorbed,
