[cisco-voip] trusted relay points

[Brian Meade]

They're basically just MTPs you deem to be "trusted".  A lot of people use
them for switching between IPv4 and IPv6.  Really not anything different
than just forcing MTP Required other than maybe just narrowing down the MTP
list.  Some people use the same setup for VPN phones/IP Communicators over
VPN so VPN clients don't have to be able to talk directly to each other.
