There is a disadvantage of having different port numbers for TCP and UDP: You can't compose a Contact header that specifies both of them. If you are listening on both TCP and UDP port 10000, then you can use "Contact: sip:1.2.3.4:10000", which lets the far end decide what transport to use. But if you listen on TCP 10001 and on UDP 10002, then you have to use either "Contact: sip:1.2.3.4:10001;transport=tcp" or "Contact: sip:1.2.3.4:10002;transport=udp", but not both. This constrains the immediate sender to use TCP or UDP, depending.
