Emergency Access (911)

[Stagemusic]

We have a CS1000M in our office and are wanting to add a different building about 8 blocks away to our phone system. The other system has an Option 11 with ITG and a signaling server. We are wanting to do away with that system and then deploy it elsewhere. We have the networking capability for the IP phones and routes. However, we are wondering about 911 and what address the Emergency people would go to in the event of a problem. Is there a way (without changing everyone's DID numbers which are spread over both locations). Any ideas?

Probably the easiest and cheaper solution is to purchase a 1FB from your telco, and have an analog phone used specifically for 911.

You can use your CLID table and use a billing number to send out for the other building that all those calls will reflect. Alot cheaper than the recurring cost of a seperate phone line just for 911.

Thanks pbxn but that is not really feasible. The office is 4 floors and over 200 people.

Thanks John.

Does anyone have any experience using pkgs 339 (ESA)? How would that work in this scenario?

ESA would work and it is pretty simple to setup. You can also have an internal set notified when somebody dials 911, which is nice because you can call the extension back and find out if it is an emergency or if somebody just forgot how to use thier phone. Not sure about your area but one place I worked was getting a bill for false 911 calls.
Once people realize that you can track down thier actual extension they start dialing more correctly. (of course you can still use TBS to track the call but this way is instant)

As far as the setup your mainly just telling the switch to override any clid tables and to push out the phonesets DID.


No the liquid coming out of your phone is NOT dialtone!

If you're not going to use an SRG or Branch Office with local trunks, the only option you truly have is to use the CLID table and a Billing number (Fax line if necessary) for that particular site.

With the SRG or Branch, you can have all 911 calls go out the trunks that are local to the phone that dialed the call.

if the remote office has a local listed number, as stated. fax line modem, alarm etc.. you can put that number in your clid table.. number spoofing.. the ss7 table will see the clid and present the NAME on the distant number.. but the local address will show on the ali at 911 dispatch.. another problem, remote office in nyc, what good would a 911 dispatcher in dallas be even if she saw the nyc number, name and address? PAY for a local number and use it for 911. that may, with a remote office mean that you need that number in your switch.. there's a dozen ways to trick the system, remember you need not only the correct "respond to" address but you need that in the remote 911 center

Thank you. The remote office is in the same city but about 10 blocks away. The 911 response would come from the same station. The local numbers are not a problem as both offices have them for alarms etc.
