I have configured a small site using an 831 doing EZVPN to a 3030 concentrator for connectivity for about five phones. Our 3030 is lightly utilized and can handle the extra traffic. The 831 is running across a .5 km wireless link using 128bit WEP. Wireless signal strength and quality are above 75% with a low retry rate. I am having some choppy audio, and am beginning to suspect the 831 cannot handle the load. Processor utilization averages 25% with spikes to 60%. I have another site in a remote area using wireless with just WEP (no VPN) and it works great for the same number of phones. Does anyone have any ideas for how to track this down? Is anyone else doing VoIP with VPN, and what equipment are you using for how many phones?
I worked with TAC to derive this from my current QoS for serial links. QoS works great and has been tested under load. A single phone call does not cause problems, but more than two and they start breaking up.

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
