since i'm stuck with ACKs to locally generated INVITEs never reaching UASes behind NATs, i tried to read tm code to find out how to make sr always send ACK to locally generated INVITE to use the same r-uri and destination set as the INVITE itself.
i found this piece of code reply_received() function of t_reply.c:
if (is_invite(t)) { if (msg_status >= 300) { ack = build_ack(p_msg, t, branch, &ack_len);
it looks to me that the desired effect could be achieved if the middle line is changed to something like this:
if ((msg_status >= 300) || "invite was generated locally by t_uac function") {
does someone know how to implement the test, i.e., is there some info in t structure that could be used to figure out if the invite was locally generated?
