asterisk users - Jan 2009 - Cisco VoIP QOS

I have currently following the instructions at-
http://www.voip-info.org/wiki/view/QoS+Cisco

I am using a Cisco 877 router with an ADSL2+ connection.

My upstream bandwidth is around 1Mbps, and my downstream around 4-5Mbps.

I have two PSTN side interfaces - atm0 and dialer0 (dialer0 is where the ISP 
details are configured and the interface that the WAN side IP is applied on)

Now which interface to I apply the QOS on? I would have thought dialer0, but 
for some reason this interface does accept is citing that it only 
has "56kbps" of bandwidth for some reason.

Now I could fix it's bandwidth at 1000kbps, but as anyone who uses ADSL will
know, this may not be a good idea as ADSL is rate adaptive, meaning that the 
bandwidth can increase and decrease due to line conditions.

What do I do?

I tried "bandwidth inherit" though I really don't know how this
command works
and it doesn't seem to make it want to 'inherit' the current status
of
atm0...

This is the nature of ADSL. but you will be fine if the customer location is
close to ADSL switch in the CO.

you can get a loop makeup report from ISP and see how long the loop is.
then, you will get an idea about the quality for the loop.
