Sorta. If talking about H.323 and no gatekeeper is in the network then
yes. If other VoIP protocols are used then you will need more ports
identified. Here is what I generally use:
access-list 100 permit tcp any eq 1720 any <--H.323 H.225
access-list 100 permit tcp any eq 2000 any <--SCCP phone
access-list 100 permit tcp any eq 2001 any <--SCCP analog trunk
access-list 100 permit tcp any eq 2002 any <--SCCP digital trunk
access-list 100 permit udp any eq 2427 any <--MGCP
access-list 100 permit TCP any eq 2428 any <--MGCP Backhaul
access-list 100 permit tcp any eq 5060 any <--SIP
access-list 100 permit tcp any range 1718 1719 any <--Gatekeeper RAS
access-list 100 permit tcp any range 11000 11999 any <--H.323 Gatekeeper
H.245
access-list 100 permit tcp any any eq 1720
access-list 100 permit tcp any any eq 2000
access-list 100 permit tcp any any eq 2001
access-list 100 permit tcp any any eq 2002
access-list 100 permit udp any any eq 2427
access-list 100 permit TCP any any eq 2428
access-list 100 permit tcp any any eq 5060
access-list 100 permit tcp any any range 1718 1719
access-list 100 permit tcp any any range 11000 11999
access-list 101 permit udp any any range 16384 32768
access-list 101 permit udp any range 16384 32768 any <--RTP(Voice
Stream)
Others can be used for QoSing a Callmanager system control protocols,
Example: SQL, ICCS, DC Directory, HIDS, etc.

Hi,solomon
you can identify voip traffic with port number ,tcp 1720 and udp from
16384 to 32767
