[SR-Users] How to use sdp_remove_media() ?

[Daniel-Constantin Mierla]

Hello,

that's strange, because the condition in the c code is:

    if(msg->first_line.type != SIP_REPLY && get_route_type() !=
REQUEST_ROUTE) {
        LM_ERR("invalid usage - not in request route or a reply\n");
        return -1;
    }

Which is clear about whether the message is a SIP reply or function is
executed in request_route. There is a condition later about the
record_route(), but it didn't get to that code...

Maybe you can share the entire request_route you had when the error was
exposed.

Cheers,
Daniel
