I have seen other QosS questions, but have some that apply to me that maybe someone can help with.
We have Main branch with 9M (X6 T1) that holds call manager and all the voice servers (IPCC, Unity).
The 6 remote branches have T1s with 768k CAR from the Provider.
The main site is configured:
set ip dscp ef
set ip dscp af31
set ip precedence 0
The remote branch:
set dscp ef
set dscp af31
set dscp default
Both the Main Branch and remote sites have the policy applied to their WAN interface with no direction (in or out) specified.
My questions are:
1. Does a direction need to be assigned to the policies, or ingress and egress policies applied to get more out of QoS?
2. Could the policies I have be made to better utilize QoS?
3. To accurately size the classes, do I need to count the number of potential phone calls from each branch to the main branch, and size accordingly, including any potential video (coming soon) calls made?
