Be careful with the linksys devices as they may not do SCCP NAT 
properly.  I personally use a Cisco 871 at home connected via EZ-VPN and 
it works perfectly.

As was mentioned, with newer phones (and newer callmanager) you can look 
at running iLBC as your codec, which may help things. Also, if you're 
not already running G.729 switch to that.

All that said, I personally feel the quality is always better using a 
real IP phone than IP communicator - I just can't find any PC headsets 
that I'm a fan of.
