I have 2 branch offices that are having voice quality problems accross a MPLS network calling corporate, each office has a T1 going to our data center and i have a 10mb metro e coming in to my corporate headquarters from the data center. There is a 3845 at the Data center a 4510 at HQ and a 2801 at one office and a 1760 at the other office. I was just going to turn on auto QoS and let it do it's thing but the CoS for Avaya dosen't work with Auto QoS. It is a simple voice network no video or anything fancy. The LAN has no congestion. I need to know what configs i should put on my devices to get the voice quality better.
