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: SIP/2.0 200 OK Via: SIP/2.0/UDP Kamailio_IP;branch=z9hG4bK02e7.7581e8a2.0;received=Kamailio_IP Via: SIP/2.0/UDP 14.14.14.58:5060 ;received=79.132.227.35;branch=z9hG4bK-ba26313a;rport=45068 Record-Route: sip:Kamailio_IP;lr=on From: sip:151355001@Kamailio_IP;tag=c75da877876e372i0 To: "092968050" sip:092968050@Asterisk_IP;tag=as24bf1176 Call-ID: 6cb855a76b6ab33736cc85a83f9d7633@Asterisk_IP CSeq: 101 INVITE User-Agent: domain name Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY Supported: replaces Contact: sip:092968050@Asterisk_IP Content-Type: application/sdp Content-Length: 354

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.
