Hi Virmantas,

you could try to one or a combination of the following: - explicitly delete the first session by calling rtpengine_manage() in the failure route - call msg_apply_changes() from Textops before calling rtpengine_manage() the second time (so the already made changes are applied and the message gets reparsed)

Thanks, Carsten

Hi,

I have a situation like this: I have kamailio with 3 NIC's. 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!
