<P><FONT face=Arial size=2>Hi all</FONT> </P>
<P><FONT face=Arial size=2>I'm having a problem with voice quality going over
the WAN. We use a 2801 on each end. Someone suggested that there
might be a issue with COS. I thought by default Cisco tags all voice
traffic as COS 5. AT&T is looking for COS 1. Am I wrong about
Cisco being tagged as COS 5? If not, then how do I change the 3750 to tag
the voice as COS 1 to match AT&T?</FONT></P>
