[cisco-voip] Emergency Response Location Mapping

[Lelio Fulgenzi]

You should not send calls to 911 out a gateway in an area that is serviced by a different PSAP, especially if it is in a different area code. As far as I know calls to 911 are only 7 digits (this is what I have been told) and if you send a 911 call out a gateway in an area with a different area code, it might actually end up showing up with the wrong address.

You can use calling search spaces to force phones/lines to grab a different 911 route pattern that uses a particular external calling mask which is a 1FL at that location. With only four, it should be pretty painless.

  The issue here is that I have four locations that are all connected back to one central location for all the phone lines ( approx 20 kms from each other).

   

  The way I thought was to have a pstn line at all locations , and use CSS to route 911 calls for that particular area out the pstn. But my contract support guys are telling me that it can be done via configs on the router at each location and still have the calls sent out from one place..

  I really don't know.  But for some reason I think someone said something about using locations in CM 6.x for some of this.  I would start looking there.  if you are using pre 6.x I don't think there is a really good way.  Did someone take a phone and move it to a new location?  That;s the problem I'm having currently.

   

  I'm looking for the best solution for E911 currently and plan to make a decision at CIPTUG this year.

   

  if the user was just EM or something like that.... then it's all based on Phone + line CSS and shouldn't otherwise be an issue.

  I overheard at one stage it is do able by writing configs on the routers and switches.

  Can any one point me in the correct direction.
