i found a changes for rever_uri() function . i am using carrierroute module to route changes. so after a query destination number , a prefix is added to Request uri and sends request. after get error first request goes to failure route and works revert_uri() . revert_uri changes to first request uri. There is a example above. Client sends : 5055066105 Servers addes prefix : 200025055066105 after t_relay if i get error goes to failure_route[3] and work revert uri : 5055066105 in kamailio V4.2.5 it gives "200025055066105" ALERT: <script>: Request Uri -0 05055066105 ALERT: <script>: Request Uri -1 Before revert 200025055066105 ALERT: <script>: Request Uri -2 After revert 05055066105 ----- Sample Code ---------------- [switchingroute]{ //$avp(69 is prefix 2002 $rU=$_s($avp(69)$rU); if(!cr_route("$avp(s:carrier)","$avp(s:domian)","$rU","$rU","call_id","$avp(s:route_desc)")) { send_reply("603", "Route bulunamadi"); exit; } $avp(s:host)= $rd+":"+$rp; t_on_failure("3"); if(!t_relay()) { xlog("L_ERR","Servis Disi"); send_reply("408", "Servis Disi"); }else{ exit; } return; } failure_route[3]{ xlog("L_ALERT","Request Uri -1 Before revert $rU"); revert_uri(); if(!cr_next_domain("$avp(s:carrier)","$avp(s:domian)","$rU","$avp(s:host)","$T_reply_code","$avp(s:domain)")){ xlog("L_ALERT","[$ci]route:bulunamadi"); exit; } if(!cr_route("$avp(s:carrier)","$avp(s:domian)","$rU","$rU","call_id","$avp(s:route_desc)")){ xlog("L_ALERT","[$ci]route:yapilamadi"); exit; } $rU=$_s($avp(69)$rU); xlog("L_ALERT","Request Uri -2 after rever $rU "); $avp(maliyet_id)=$avp(s:route_desc); $avp(s:host)= $rd; t_on_failure("3"); if(!t_relay()) { send_reply("408", "Servis Disi"); exit; }else{ exit; } return; } -- View this message in context: http://sip-router.1086192.n5.nabble.com/upgrade-V4-2-5-to-V3-1-Build-error-… Sent from the Users mailing list archive at Nabble.com. _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
