I'm sending INVITE to first provider over NIC1. Before sending INVITE I use rtpengine_manage to rewrite sdp body with IP that is on NIC1: rtpengine_manage ("replace-origin replace-session-connection direction=intvlan direction=prov1 ICE=remove"); If first provider fails i want to send INVITE for the same call to second provider. But if i use like this: rtpengine_manage ("replace-origin replace-session-connection direction=intvlan direction=prov2 ICE=remove"); or (because ip of prov1 is allready set): rtpengine_manage ("replace-origin replace-session-connection direction=prov1 direction=prov2 ICE=remove"); rtpengine ignores my changes as said in documentation: "The direction must only be specified in for initial SDP offer; answers or subsequent offers can omit this option." and if I try to set ip like this: rtpengine_manage ("replace-origin replace-session-connection media-address=X.X.X.X ICE=remove"); SDP body is doubled: it leaves old values and adds the new one. What i'm doing wrong or how can I rewrite SDP for second time? Thanks in advance for answer! _______________________________________________ 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 -- Carsten Bock CEO (Geschäftsführer) ng-voice GmbH Schomburgstr. 80 D-22767 Hamburg / Germany http://www.ng-voice.com mailto:carsten@ng-voice.com Office +49 40 5247593-0 Fax +49 40 5247593-99 Sitz der Gesellschaft: Hamburg Registergericht: Amtsgericht Hamburg, HRB 120189 Geschäftsführer: Carsten Bock Ust-ID: DE279344284 Hier finden Sie unsere handelsrechtlichen Pflichtangaben: http://www.ng-voice.com/imprint/ _______________________________________________ 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
