I am a newbie to the the 2821 as my voice gateway and have never setup QoS on the router. We have moved to a new service provider that is a SIP trunk that connects to our router. The router then has dial-peers that go back to our CallManager 8.0 implementation. Everything works fine, however now I am beginning to experience and hear about some QoS issues with call Quality. Being that I have never set QoS up on a router before are there any suggestions to start the process on this. The router is the entry point for the network as well as the default gateway for the network....Router on a stick config. The SP comes in on Gi0/0 and my internal network is setup as sub-interfaces on Gi0/1.10, .100, .101, .102, .103. the .102 network is my voice network.
Thank you in advance for your input.
