[cisco-voip] Centralized Unity QOS

Most of our IPT network is connected via high speed Metro Ethernet.
Only have 2 IPT sites across WAN links so any pointers would be
appreciated.  (frame at remotes to ATM at HQ)

I moved this to the top as I noticed some physical errors on the remote
T1.(That's an obvious problem).

7) Not doing phone calls between sites but regions and locations are
configured.  Codec is G711 and I just changed location max audio
bandwidth to 768 (was 512).

What does the ACL Voice-ACL have in it?

How is the frame relay traffic shaping (FRTS) setup,
if any? Can you post a show run of the T1/frame
interface and related class-maps for frame? And a show
frame pvc ### from both sides. Post the class-map and
policy-map used for QoS also. 

Are there any physical interface errors on either
routers WAN or LAN interfaces, how is LAN going to
Unity server? QoS on the Switches? Any errors on the
switchport connecting to the unity server? 

Anyone complaining of quality on phone calls between
the sites, besides unity traffic? 

What codec is used between the sites (are regions
configured)?
