[2] RTSP は独自の符号は50番台を使うことで衝突を防いでいます。 (RFC 2326 7.1)

''httpd-2.0/modules/http/http_protocol.c'' <http://www.apache.jp/viewcvs.cgi/httpd-2.0/modules/http/http_protocol.c>

- [4] SIP/2.0 は、 RFC 2543 では六百番台以外は 80番台を使うことで衝突を回避すると書いてありましたが、 RFC 3261 でその一節は消えて、実際他の番号に進出しています。 (で、見事に HTTP/1.1 (RFC 2616, RFC 2318) と衝突しています。。。)
