[cisco-voip] E911 (CER or 911ENABLE), SNMP and port locations

[Ed Leatherman]

Sean made a good point, I overlooked that option. You can configure
locations based on IP address and also based on directory number as well.
The way our network is setup, location by IP wouldn't work so we do it by
switch port.

I do location by extension for dorms, since there is only 1 appearance of
each extension and they are all VG224 ports rather than switch ports.
