Hmm... this is strange, because the 3GPP specs (3GPP TS 29.060 V8.5.0, Section 10) states "UDP/IP is the only path protocol defined to transfer GTP messages in the version 1 of GTP. [...] The UDP Destination Port number for GTP-C request messages is 2123. It is the registered port number for GTP-C. The UDP Destination Port number for GTP-U request messages is 2152. It is the registered port number for GTP-U." Which one is more credible?

Regards,
Rayne
