I really know next to nothing about 3G. […] Still not sure about 3G and IuUP specifically, but more generally speaking, if some application of RTP says "don't use RTCP", they still typically require or at least expect an even UDP port number for RTP, and the corresponding odd port is still reserved for what would have been RTCP. The way to handle such scenarios with twrtp is to let twrtp library bind to both UDP ports, let it swallow all packets that arrive on the odd-numbered port, and let it parse them as if they were RTCP. But don't send out any outgoing RTCP packets (which the library won't do on its own until and unless the application requests RTCP output and configures SDES), and simply ignore the existence of the built-in RTCP receiver and parser. Section 5.6 of the manual says basically the same thing.
