I'm experiencing poor voice quality between my home office and a remote. The offices are connected via a dedicated T-1. The home office is using a 3745 and the remote is running a 3725. QOS is setup as follows:
class-map match-all termserv
match access-group 103
class-map match-all video
match access-group 112
class-map match-all voice
match ip precedence 5
!
policy-map wan-outbound
class voice
priority 350
class termserv
bandwidth 375
class video
bandwidth 256
This map is applied to the serial interfaces on the routers.
Output of show policy-map:
Policy Map wan-outbound
Class voice
Strict Priority
Bandwidth 350 (kbps) Burst 8750 (Bytes)
Class termserv
Bandwidth 375 (kbps) Max Threshold 64 (packets)
Class video
Bandwidth 256 (kbps) Max Threshold 64 (packets)
AutoQos is enabled on the 3550 switches on both ends. Not sure where to start.

You're almost there. Try "show policy-map interface"

Well, the problem is not with your Priority Queue bandwidth configuration. You have no drops in that queue.
Can you set up a call that has poor quality. Then on both ends paste output for "sh call active voice brief"-->just pull out the info for the call in question. There should be two legs associated with the call.

Also, we'll need the "show policy-map int" from the other side as well...
