The servers are dedicated to just dial dictate. We changed the recording format to uncompressed PCM and the quality jumped through the roof. I am now doing a audio recompression pass on another computer. This gives us much higher quality than recording to the more compressed formats on the dial dictate servers. It appears that there are some major quality issues that are occurring when recording to some of the more compressed formats using dial dictate.
For reference our Dial Dictate servers are as follows.
Server 1

Server 2
