911 Laws

Hello, Can someone point me in the right direction on this question? In my Cisco IP telephony class, my instructor made a very serious emphasis that 911 has very big criminal liabilities if it does not work on every phone in the company.

I need to find where this is stated in law or case law so I can show it to my employer. Does anyone know where I should go or ask (other then our company attorny?).

Thank you in advance

If I were you, I would go directly to your company legal group. If they make the descision to block it on particular phones, make sure you get it down in writing to cover yourself when the law suits start coming in!
 
I agree in checking with local state legislature. I have my doubts..

In Canada, you can still have intercom use type phones restricted to internal calls only eg. Hotel Lobby. You can have automatic ringdown courtesy phones to Taxis etc. You can install ringdown weatherproof phones without keypads.

In Canada the rule was, if a phone can access an outside line by key appearance or by dial 9 + local call it must be able to reach 911. That was a real problem with old Tie Meritor or other Key systems that used a simple toll restriction that did not allow 0, 1 as first or second digit. Previously, Local exchanges under the North American Dial Plan could not have 0 or 1 as the middle digit of the exchange.-NiX NoX. This simple toll-restriction blocked the sets ability to dial 911 and had to be removed or a more elaborate form of toll restriction used.

Sorry
Ancient History Lesson

N1/0X was known as Nix Nox which was an Area Code. 1 or 0 was the middle digit. Area code relief changed that and we now have area codes without 1 or 0 as the middle digit.

NNX is a local exchange.
N could be any number except 1 or 0 and X could be any number.

0 or 1 as simple toll restriction prevented:
0+ (Operator Assisted)
1+NNX-XXXX (Long Distance)
1+Area Code + NNX-XXXX (Long Distance)
011 International LD

Now with 10-digit local, coresident area codes and 911 this form of toll restriction is obsolete and can't be used.

Requiring 911 access is a jurisdictional thing, and is usually spelled out by the PU code or other state statute.

The default disclaimer has something like ... where technically feasible...

I don't think it is required in every state yet because I have been having "soon you will need to implement this" discussions with my vendors over the last year or so, and they make an "appliance" that sits on your PRI and you can build a database in it that tells 911 where to go for each phone. On standard copper trunks it sends out the ID of the trunk no matter what extension you are at, which is really obnoxious in an organization as big as mine!
 
@Donb01 what is the appliance? We would like to have better locations on 911 calls but setting up PS/ALI with a vendor will increase our monthly phone bill by 60%ish.

Thanks
 
Who is the "they" that makes the "appliance"?

I sent an E-mail to the tech who was trying to sell it to me a year or so back to have him refresh my memory. I'll post what I get. I know exactly how it works but just can't remember the name of it.
 
Even extensions that are normally internal only can be allowed to have emergency access.

There are various ways to do this depending on your platform.

Make 911 a non DDI extension on permenant call forward to external trunk+911

Make 911 an abreviated dialing code that sends call externally to 911

You can even have 911 calls delivered to security or reception to be handled from there.

No need for a box of tricks from an external supplier just get creative.

umm,it IS supposed to do that, right??
 
It all depends on the PBX capabilities, some do and some don't! Not all have PRI capability either...

There is a free webinar for the Michigan Users Group on the legislation that is being enacted there later this yesr.

This is a review of the proposed law, the comments Avaya Filed t the PUC and how you can deal with 911 on a general basis, not a sales pitch. All are welcome

Guessing that Mesa means AZ, it's not in your state yet, but there are some PBX/911 rules moving across the country. Most seem to belong to buildings of 40,000 square feet. Here's the latest quick reference
Any PBX or key system worth its salt has provisions for handling 911 calls. If your VoIP dial tone provider company doesn't, you need to make sure you do. If that means a land line tied to the system just for 911, then that's a solution you'll have to provide for.

It would seem to me that it's not an option you'd have to prove to your employer, it's a matter of safety.
