[cisco-voip] phone hardware / LSC question - 8945

[Erick Wellnitz]

Auto Network Detect is indeed enabled.  According to the following link,
the phone pings the TFTP server.  If there is no response the phone should
initiate the VPN connection.  I'm not very familiar with proxy arp so does
that mean the router would respond to pings to my TFTP server?

Alternate TFTP is also set.

The problem with turning off Auto Network Detect is that many of the
intended users of the phone vpn are non-technical so it needs to be plug
and play.  Is there a knowledge base of some of the routers that work well
with phone VPN?
