I have a Shoretel voip pbx. I have a remote user that connects via Site to Site vpn (Cisco ASA 5505 to Cisco ASA 5510).

How do I properly setup Qos over this link.

Here you go don't forget to change the tunnel group name to match yours ("show run tun" will tell you).

Petes-ASA(config)# class-map Voice-Traffic
Petes-ASA(config-cmap)# match dscp ef
Petes-ASA(config-cmap)# class-map Data-Traffic
Petes-ASA(config-cmap)# match tunnel-group Remote-VPN <<<Yours will be different!!
Petes-ASA(config-cmap)# match flow ip destination-address
Petes-ASA(config-cmap)# policy-map Voice-Policy
Petes-ASA(config-pmap)# class Voice-Traffic
Petes-ASA(config-pmap-c)# priority
Petes-ASA(config-pmap-c)# class Data-Traffic
Petes-ASA(config-pmap-c)# police output 200000 37500
Petes-ASA(config-pmap-c)# service-policy Voice-Policy interface outside
ERROR: Class Voice-Traffic has 'priority' set without 'priority-queue' in any interface
Petes-ASA(config)# priority-queue outside
Petes-ASA(config-priority-queue)# queue-limit 2048
Petes-ASA(config-priority-queue)# tx-ring-limit 256

Is the site to site vpn over a private backbone or over the Internet?  Given it is site to site, I am going to assume Internet.  Keep in mind that once you hit the Internet, you are at the mercy of the Internet where you are no longer control of your packets.

It is over the internet.  Let me explain what I am hopeing to accomplish.

Since this is for a remote worker, I want to prioritize the viop traffic over normal data so that even if the worker is downloading a large file that his voip traffic will not suffer.  I know I can not guaranty the same accross the entire link, but if I could protect the worker from himself that would be great.
