[cisco-voip] Cisco Unified PhoneProxy+7970 vs. 871 route+7970 r vs. Cisco VPN Client+IP Communicator

[Robert Kulagowski]

Any thoughts on the relative merits of the above combinations?  We 
currently deploy the VPN client + IP Communicator for home users, but 
there are complaints of call quality issues (we use CM 4.1.3sr5 and 
g.729).  Since we can't switch to iLBC we're looking at alternatives.

 From what I can gather, the PhoneProxy would still encrypt all traffic 
over the Internet (control and voice), correct?

Is it any more "efficient", packet-wise or whatever, than a full-blown 
VPN tunnel configuration that you'd get with a 871?
