We have a couple of UCx50's we are using in a campus environment. The only ANI/AlI 9-1-1 information from the SIP phone we get is from the main phone number miles sway. Is there any way that ANI/ALI for 9-1-1 can be established for each of the remote locations without having an actual 10-digit number a those remotes? My best guess is no.


911 and ANI can be a bit confusing. First, if you are using analog trunks, the number that will show up at the PSAP will be the number assigned to it by the telco. Old technology.......old results and very little you can do on the UCX to change that (I think).

If you have digital (PRI or SIP) you have options. The way I set my systems up is first to create an outbound route just for 911 and check the box that says Emergency Route. Then you can go into each user and input whatever 10 digit number you want to send out in the Emergency CID field. Then remove any reference to 911 in your regular outbound routes.

This way, whenever someone dials 911, the UCX will match on your emergency route and because it is flagged as an emergency route, will send the number you have in the Emergency CID field. This is my standard setup whenever I have users with remote phones (especially at home). Works like a charm every time.

I have never tried this setup on analog trunks but if that's your situation, give it a try and see if that works.


Thanks Telcodog, but the remote locations do not have 10-digit phone numbers, only SIP phones from the main server, which identifies the server location, not the remote location. I just don't know of any way to make the server identify the remote location, because there is no ANI/ALI spill from the phone/internet company, only the main numbers and addresses from the server located miles away. Thanks again.


this is how I would handle a remote.
Purchase a Voip DID with 911 service (arround $2 a month) for each area needed
Build an 911 outbound route for each location
In the dial patterns for each route include the extensions range in the /callerID field
example: remote location a extension range is 4100-4299 the callerid field would contain 4[1,2]XX
remote location b extension range is 5500-5599 the callerid field would contain 55XX
move each 911 route to the top of the Add Route column


Hey didn't know they had that service for 9-1-1. (Spectrum?)THANKS! I'll give it a shot. To be continued......
