[cisco-voip] Centralized Unity QOS

[Philip Walenta]

OK, the major things here are:

1.  You need FRTS for QoS to work.

2.  You *must* use Multilink PPP over this link, as Frame Relay and ATM have
no inherent method of transmitting frame-relay style messages.

Here's a link that shows what you need on both sides:

86a0080101210.shtml

You can use the ACL's you've built already in place of the ones in the link,
but the rest you will definitely need.

Just looking at the output drops listed on the interface is a dead giveaway
that FRTS is needed.

I'm also including this link which talks about how to properly set all your
Frame relay map class settings correctly based on the PVC and link size.

Most of our IPT network is connected via high speed Metro Ethernet.
Only have 2 IPT sites across WAN links so any pointers would be appreciated.
(frame at remotes to ATM at HQ)

I moved this to the top as I noticed some physical errors on the remote
