Unable to Update Headers in failure route which were build in request route

by Sunil More

Hi All, I am trying to have a failover route where if a initial relay fails , i can forward the same request to a second provider. I am using a certain set of headers that help to authenticate over my providers. I am trying to update those headers. However update and removal both fail. The headers are still present. Please help me understand if i am wrong. Here's the code. ..... route(GET_CREDENTIALS); } remove_hf_re("X-*"); append_hf("X-Src-IP: Trusted\r\n", "Call-ID"); append_hf("X-Identity: $hdr(X-Calling-User)\r\n", "Call-ID"); append_hf("X-Auth-ID: $avp(siptrunk_username)\r\n", "Call-ID"); $avp(realm) = $fd; $rd = $avp(siptrunk_domain); $var(duri) = "sip:"+$rU+"@"+$avp(siptrunk_proxy); $du = $var(duri); t_on_failure("UAC_AUTH"); if(!t_relay()) { sl_reply_error(); exit; } } failure_route[UAC_AUTH] { if(t_check_status("(4|5)[0|8][0|2|3|4|6|8]")){ xlog("L_INFO","failover testing"); revert_uri(); route(FAILOVER); } if (t_check_status("40[17]")) { xlog("got challenged \n"); uac_auth(); xlog("L_INFO", "Return code is $retcode"); $rd = $avp(siptrunk_proxy); t_on_failure("UAC_AUTH"); t_relay(); } } route[FAILOVER]{ xlog("L_INFO","doing failover now.. "); if($avp(failover_routing_id)!=$null) { $avp(outbound_routing_id)=$avp(failover_routing_id); xlog("L_INFO","Failover carrier credentials are.."); route(GET_CREDENTIALS); #not adding headers now remove_hf_re("X-*"); append_hf("X-Src-IP: Trusted\r\n", "Call-ID"); append_hf("X-Identity: $hdr(X-Calling-User)\r\n", "Call-ID"); append_hf("X-Auth-ID: $avp(siptrunk_username)\r\n", "Call-ID"); $avp(realm) = $fd; $rd = $avp(siptrunk_proxy); $var(duri) = "sip:"+$rU+"@"+$avp(siptrunk_proxy); $du = $var(duri); xlog("L_INFO","Destination Uri from failover is : $du"); t_on_failure("UAC_AUTH2"); if(!t_relay()) { sl_reply_error(); exit; } exit; } } failure_route[UAC_AUTH2] { if(t_check_status("(4|5)[0|8][0|2|3|4|6|8]")){ xlog("L_INFO","Failover failed. cancelled call "); exit; } if (t_check_status("40[17]")) { xlog("got challenged \n"); uac_auth(); xlog("L_INFO", "Return code is $retcode"); $rd = $avp(siptrunk_proxy); t_relay(); } exit; } Thanking You, Sunil More

issue with sending "delete" to rtpengine for cancelled branch

by Vasiliy Ganchev

Hi folk! Have an issue, and do not see the obvious way how to solve it, maybe i'm missing something. The call scenario: UA-A (hard phone, no rtpengine) call ->> UA-B (has 2 registration: hard phone (no rtpengine) and WebRTC based web phone (here the rtpengine is called, in branch_route)) When Kamailio fork call to UA-B, for the branch with WebRTC UA, I do rtpengine_manage (rtpengine receive command "offer" and allocate 4 ports). If UA-B answer via hard phone, Kamailio Cancel branch to WebRTC phone, and here I need to do rtpengine_manage (to send "delete" command to rtpengine). But as I see Kamailio CANCEL all nonanswered branches automatically (I see no place where to call rtpengine_delete) Any suggestion how to cope with such issue? cheers! -- View this message in context: http://sip-router.1086192.n5.nabble.com/issue-with-sending-delete-to-rtpeng… Sent from the Users mailing list archive at Nabble.com.

msilo dump with non 2xx answer

by Péter Barabás

Hi, I set instant message store&forward in kamailio using MSILO module. It works fine in many cases. We have special message handing (encryption in "session"), i do not go into detail since it is not necessarily to solve the problem. So there are situations, when the offline receiver should get a MESSAGE and will acknowledge with 4xx status code, like 493: the original message is stored in silo table and when the receiver will be online, it will be dumped and he will send 493. Question: how can I delete the message from silo table with MSILO (since it is not 2xx) and how can i forward this ack message to the original sender instead kamailio? Thanks.
