[cisco-voip] Emergency Response Location Mapping

[Matthew Saskin]

Specific to what was mentioned before, you can configure ERL information 
as switchport descriptions on your access layer switches.  In turn, CER 
can poll these switches via SNMP to associate a port (and the MAC of the 
phone) to the specific ERL for call routing.

Realistically, unless you are in a large campus serviced by different 
PSAP's, etc., CER is likely overkill.  A single POTS line at each 
location and separate 9.911 route patterns should suffice.
