We're putting 6 IP phones on a 1924 which is connected via fastethernet to a 2621 which is connected via T1 to a 7206. This 7206 is connected to a cat5505/RSM which is connected to a cat4003 where the PBX is attatched.
Do I just need to have QOS on the T1 inorder to insure good phone reception? The PBX is handling all the call setup and dialer maps.
Here is what I was going to config in the 2621:
class-map match-all VoIP-Control
match access-group 100
class-map match-all VoIP-RTP
match access-group 101
description T1 connection to 7206 S6/4
ip address 126.96.36.199 255.255.255.128
service-policy output VoIP-Policy
