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

Hi Inaki,
I'm getting the below error when using t_relay(); in
onreply_route[7]....Maybe i need to you something else?
Mar 13 13:11:03 [27785] DBG:core:find_cmd_export_t: <t_relay> not found
Mar 13 13:11:03 [27785] DBG:core:find_cmd_export_t: found <t_relay>(0) in
module tm [/usr/local/lib/opensips/modules/]
Mar 13 13:11:03 [27785] CRITICAL:core:yyerror: parse error in config
file,
line 728, column 9-10: Command cannot be used in
the block
^^^^^
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.
