Guys,
Wondering if someone could enlighten me on which match statement to use to
match voice traffic:
From what I can see you can match RTP payload only
match protocol ip rtp 16384 16383
match protocol rtp audio
I'm not really clear what the difference is between these two, if there is
one?
Then all VOIP with an ACL
match access-group 100
access-list 100 permit udp any any range 16384 32767
access-list 100 permit tcp any any eq 1720
Just wondering if anyone can enlighten me as when it's appropriate to use
what; is it best to use the ACL unless the question specifically mentions
even numbered ports or voice payload etc or if the question just states
voice would any method be acceptable?
Cheers,
John
