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

[Louis Marascio (lmarasci)]

Robert,

PhoneProxy can encrypt signaling and voice traffic, that is correct.
Signaling will be encrypted w/ TLS and voice media will use SRTP. HTTP
traffic, for IP phone services etc, will NOT be encrypted. This is one
differentiator that the 871 solution has. 

Take care,

Louis

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?
