We have two 1760 routers connected via a T1. On the LAN side there are 3rd party VOIP gateways installed. What we need to achieve is to implement QOS to prioratise voice calls going through the T1 link.
I have put together the following config. Appreciate if some one can confirm that this solution will work.
!
hostname ABC
!*********
Class-map match-all voice-signaling
match access-group 103
class-map match-all voice-traffic
match access-group 102
policy-map VOICE-POLICY
class voice-traffic
priority 100
!-- queue is assigned to "voice-traffic" class with (based on ACL in
!-- class voice) with max bandwidth = 100 Kbps.
class voice-signaling
bandwidth 8
class class-default
