[cisco-voip] Smallest Cheapest VGW

[Lelio Fulgenzi]

Definately, the DID service is the one that goes with ER. That's an expensive route for both the PSALI service you have to purchase from the carrier as well as the ER service from your telephony vendor. 

But I'm 99.9% sure that if you use an LDN on your PRI service (as far as I know, an LDN is a number which has specific handling rules unlike DID which is part of a group and office route) you can modify the emergency database record.

  I believe this is how the E-911 server works.  Relys on having
  different emergency locations assigned to different DIDs.  The E911
  server then routes calls through the appropriate RP that changes the
  calling party number.

  I'm not sure if all telcos support this at this time.

If you can get this, than you can configure route patterns appropriately so that 911 calls from these phones still go out your main site but are tagged with the site specific number, therefore, bringing up the right emergency record.

So I'm thinking I may want to put a little VGW with a FXO over there for 911 Calls.  Not because I'm worried about the Fiber but because I want 911 to have the correct address 2600 not 2611.
