Routing based on CLI

Hi there I have a customer running 8720 with a number of remote gateways. What they are looking for is a way to route a common number to a local emergency point on each of their sites. For example if I am on site 1 and dial 555 it routes to a number on site 1. If I am on site 7 and dial 555 it routes to a number on site 7.

This will work fine in theory using ani and vectoring given that each site has a different extension range, so by looking up the ani in a vrt I can then route to a specific number based on that.

Where the problem lies is that I a person from site 1 goes to site 7 and logs their phone in there and has a need to dial 555 in an emergency then based on the extension cli it will call an emergency number on site 1 rather than site 7 where the person actually is located at that time.

Does all that make sense and if so, can anyone suggest any other way to do this or some way to work around this issue, which I dont think will be a major problem but one that has been mentioned in discussions.

Regards

The idea is that you can use next command:

ch ars digi xxx location zzz

so, in each location you can convert your number 555 to the real number of your emergency point and route it to tht number.
 
RFLundgren,

if you have cm3 with multi-location dial plan implemented, you can add an udp entry for this emergency number and use location-based prefixes to route calls to local emergency station. alternatively you can use location-based ars digit conversion to achieve the same goal without having to bother with changing your whole dialplan. in this case you don't even need to know an extension number, only its location. and if this customer's network is properly implemented, all location numbers should be set up already.
 
Thanks for all of the ideas on this one. Time to go and do a bit of reading now I think.

Cheers

Richard
