Need some assistance providing QOS on a point-to-point leased line for VoIP traffic to/from a remote office.
Per an earlier forum recommendation, I added the following to the router configs (with a vague understanding of it).
class-map match-all VOIP
match access-group name VoiceOverIP
!
policy-map SET_PRECEDENCE
class VOIP
set ip precedence 5
Now that I have read up on this subject a little more, I'm more confused. If I'm not mistaken, the above commands do nothing without a corresponding access-list command to define the traffic, correct?
If that's the case, how would I define the traffic?
From what I've been told of the phone system:
- audio is carried over ports 5000-5064 (not sure TCP/UDP),
- TCP 5566, UDP 5567, and TCP 5570 are used for signaling
The above info makes me believe the phone is SIP based (it is an Intertel Axxess system) which commonly uses TCP/UDP 5060 (I think).
So far, I'm leaning towards a command similar to:
access-list VoiceOverIP permit any any range ???
Then I get stuck .. perhaps I'm over thinking this. Any (and all) help appreciated.
