[cisco-voip] Emergency Responder Setup ? - Part 2

[Dark Fiber]

My setup / need for CER is pretty basic to be honest.  We are not
having to deal with updating location databases or anything at the
provider level.

I simply have 12 small locations that are geographically dispersed and
reside in different areas with different PSAPs.  However they all use
Cisco IP Phones and connect to a centralized callmanager cluster and
for now use centralized PRI's.

I got two DID's if you will for each location, these are setup by the
service provider and are tied to the locations address.  I simply need
to take a 911 call from one of the remote offices and convert the
called party number to one of these DID numbers for that location so
that it reaches the correct PSAP, and it provides a method for the
PSAP to call back.

So I am fortunate in that regard that I am not having to do station
level stuff or PS/ALI type of stuff.  I could have done this all to be
honest with callmanager alone, except for the PSAP call back.

Having CER offers us the ability to do more then this, and we are
already planning on leveraging more of what it can do in the near
future but for now the needs are minimal.

Many will tell me how bad it is to rely on central locations and not
have local pots lines and gateways in case the wan goes down and I
agree, however these are not traditional offices / remote locations.
Some of what we will use this for is small home offices with only 1 or
2 people, and the cost of a gateway device capable of supporting a
pots line and SRST is simply not viable.

They have pots lines for personal usage they could use, we just want
to make sure that if for some reason they are a guest to their home
were to grab the cisco phone and make a 911 call that it will work and
get them to the right PSAP.

Appreciate all your help and openess in discussing everything with me.
