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

[Matt Slaga (US)]

The only benefit you may gain is if the ISP happens to be the same as
the corporate office ISP and they offer some type of SLA on QoS.  The
871 could appropriately mark the traffic to ISP required settings.
Otherwise, you are increasing overhead on the voice traffic.  Based
solely on voice quality and not on end-user computer needs, I would pick
PhoneProxy over a VPN tunnel anyday.

Thanks for the information on the encryption.  How about the above?  I'm

just trying to determine whether there would be anything gained and if 
it's possible that the user experience using the phone proxy vs. a full 
VPN tunnel would be worthwhile.

I thought that reducing CPU on the laptop might be a plus, but if we're 
encrypting voice packets then there's no gain there.
