Re: [SR-Users] Accessing SDP changes

You have to execute the function in request_route {} (or sub-routes executed from there) -- don't executed it inside branch_route or failure_route (or sub-routes executed from there).

Spoke too soon there - it works for initial requests, but then subsequently does not work for invites. The function complains it is not being called from a request route.

Any ideas?

    Hi Pete,

    you could try the following:

    sdp_remove_transport("RTP/SAVP");
    msg_apply_changes(); // from textopsx
    sdp_get("$avp(foo)");
    xlog("$avp(foo)");

    I believe, that should do the job.

    Thanks,
    Carsten
