rtpproxy module readme gives impression that udp transport is the only possibility:
4.1. rtpproxy_sock (string)
Definition of socket(s) used to connect to (a set) RTPProxy. It may specify a UNIX socket or an IPv4/IPv6 UDP socket.
if that is the case, what is the justification for it, i.e, why is tcp (and better yet tls) transport not supported?
