Hello, I have discovered that calling rtpproxy_manage for a failure response will cause a segfault if certain flags are passed. E.g. A "488 Not Acceptable Here" response that calls "rtpproxy_manage("fco+SP") during a failure_route will crash. This is because the OP_DELETE operation does not initialise the flags variable. See rtpproxy.c:1119 (rtpp_function_call(...)) I've attached a patch that will only add items to initialised lists. I assume that no flags are required for a DELETE operation, but please confirm this and review! Regards, Hugh -- Hugh Waite Principal Design Engineer Crocodile RCS Ltd.
