Dear Sir,

My last issue is the following...The asterisk server replies by a second INVITE that contains T38 in SDP to kamailio...Asterisk continue retransmitting the INVITE to Kamailio with no reply from it as you can see below:


Retransmitting #6 (no NAT) to Kamailio_IP:5060:

Kamailio enter in the following function:


onreply_route[7] {


if (status=~ "200"){
t_on_failure("1");
force_rtp_proxy();
}
exit;
}

I would like to know please what could be added in the onreply_route[7] in order to accept T38 negotiation and let the FAX go through

Regards

                                                    ^^^^^
                                  The error IS clearle explained, isn't?

Please check the doc about t_relay():

 http://www.kamailio.org/docs/modules/devel/tm.html#id2506628

 "This function can be used from REQUEST_ROUTE, FAILURE_ROUTE."


You can't use t_relay in on_replyroute (in fact you don't need it at
all, t_relay is used to send *requests*).

Again, please read the documentation and tutorials instead of trying
anything with no reason.

Regards.
