Hi All & Anthony,
One more query with regards to my initial qns of matching Voice packets.
How about this 3rd method
3.) class-map VOIP
match ip rtp 16384 16383
Is it the same as the previous 2 of matching Voice packets?
1.) ACL
permit udp any any range 16384 32767
or
2.) NBAR
class VOIP
match protocol rtp audio
Happy New Year every1 8)
Cheers
Nit
