it depands on what you want to match:

ip access-list 100 permit tcp any any eq 1720 this will match only the H323
TCP signaling

ip access-list 100 permit udp any any range 16384 32767 this will match the
RTP itself

ip access-list 100 permit udp any any eq 5060 this will match SIP signaling

Signaling is not a lot of traffic but the RTP on the other hand is a lot of
traffic.
