Hello. I'm attempting to provide some priority (not exactly QOS) on a
Cisco 827 for VOIP. The trouble I'm having is portraying correct
bandwidth so that the router can prioritize packets for an asymetric
line. It's ADSL 1.5m down, and 256k up.

Our VOIP partner has provided me with the info that the TOS=12, and I
put precedence critical on anything tos 12. I'm really only concerned
with overloading the upstream bandwidth. If our customers are eating
up 1.5 or a 3.0 mb ckt, they need to look at something besides DSL for
internet.

For testing, I have 1 IP phone (Cisco 7960) and 1 laptop. The phone
uses skinny (some devices use MCGP, but few customers have these) to
connect to an asterisk box. I ftp a file up to a server, thus
overloading the upstream.

Calls are pretty choppy. Any help would be greatly appreciated.
