QOS on VPN Server router for ip communicator

I have a Cisco CUCME 2911 with Voice and Data and configured as VPN Server to the internet over a 1mbit connection.
 I installed Ip communicator and VPN client on my laptop to access the site remotely by VPN Client.The problem is that The Voice traffic gets degraded when I upload
large files. Pings time out as well.

I need to configure QOS policy on the router but i don't know how can i match the voice traffic of the IP communicator to give it the priority . I appreciate if there is a template config
I have a dialer interface for the Internet
