We need more information. Do you want the _phone_ to place the call, or do you just want to be able to install something like a no-dial phone and have it connect to 911 when the receiver is lifted? If the latter, you can order from the phone company (or configure on a PBX) a "ring down circuit" to the 911 number. This is more reliable and less subject to tampering than an autodialer phone.
Alternatively, you can get a hotline dialer to attach to the phone which will automatically dial a pre-programmed number when the receiver is lifted.
Note that, in the US, even disconnected phone lines have the ability to dial 911; thus, another option would be to have a phone line installed, then disconnect service and leave a phone attached to it. I believe that the same applies to cellular telephones without service contracts. I don't know if this applies in areas without 911 service, however.

Most likely, Verizon was either clueless or lying and they can provide a ring down circuit for 911 calls only. Failing that, and assuming that you don't have a PBX and want this to work directly on a POTS line, order two red no-dial phones (you might be able to find another vendor with better pricing; I just posted a link to the first place that Google found) and a hotline dialer. Don't get long-distance service on the line and don't allow incoming calls (or, at least, disconnect the ringers in the phones); this will prevent someone from taking an incoming call, waiting for the caller to hang up (which would return a dial tone), and then placing an outgoing call using a separate tone dialer or by using the switchhook.
If you only want the line to be able to dial 911, you should be able to disconnect the service after it is installed and have 911 still work, though you will want to verify this ahead of time with the state or city department of public utilities. Don't mention this to Verizon, as they probably won't appreciate the idea.
