We tried that option, at least in our area verizon wouldn't do it, they said we had to get the PS-ALI service. <br><br><div><span class="gmail_quote">On 5/15/07, <b class="gmail_sendername">Lelio Fulgenzi</b> <<a href="mailto:lelio@uoguelph.ca">

<div><font size="2">Something you can consider as an alternative is asking your
PSTN provider to update the ELIN records for you. For example, if you don't need
dynamic ELINs and callback, and you have a short number of them, you can add
LDNs on your PRI/megalink service and have the records updated for those numbers
only.</font></div>

offer this service and you have to be using PRIs, etc, but it might be an option
for you. </font></div>

<div><br></div>Anyone have info on a reputable company that handles PS-ALI

them?<br><br>I have a regional campus that needs maybe 15 ELINs, and Verizon
will only sell a minimum of 80 records, which for the size and budget of the
campus is something they are resisting paying for. We can't add them to our

<div dir="ltr">It's a bit off topic for this list but may be the only place
where hands-on VoIP/E911 projects might be discussed, so I'd like to
hear what others say too.</div>
<div dir="ltr"> </div>
<div dir="ltr">There are whole companies devoted to this task and you are
right, it is a major task and can be a hassle. It's going to depend on
the state-supported E911 infrastructure you deal with, so look up each
state you need to do this for. A "selective router" in the e911
infrastructure routes calls to the proper PSAP and each PSAP has a PS/ALI
database. For example, in Massachusetts there are 2 selective routers
and 278 PSAPs. The MA PSAPs have a deal with Verizon to
be the only PS/ALI uploader so we had to do our data uploads through
Verizon. We had to use Kermit over a modem, but I believe they
are updating this process. You will need to press your service
provider for information, but you have to know the right questions to ask.
</div>
<div dir="ltr"> </div>
<div dir="ltr">We only had to do two PSAPs. Since each state's E911 is run
independently, you're going to have to find out what needs to be done for
your case/s. Within CER you generate the upload files, and may need to
tweak them for the PS/ALI formatting (hopefully not too much). Hint -
generate one of each NENA format and you'll be ready when they tell you you
sent it in the wrong format. </div>
<div dir="ltr"> </div>
<div dir="ltr">At some point you will need to deal with each PSAP to do
testing, so get prepared and know which ones you'll need to contact.
As a professional courtesy, you don't want to dial 911 for testing without
calling ahead first. </div>
<div dir="ltr"> </div>
<div dir="ltr">Here's a Vz link that I think someone on this list posted
recently. It shows what you should be looking for from your provider,
and lets you start building a list of questions to ask:</div>

</a></div>
<div dir="ltr"> </div>
<div dir="ltr">Also check out the NENA website and when you think you
need a break from it all lookup the Next Gen 911 (ECRIT) project being
defined in the IETF and googlable in combination with Henning
Schulzrinne's name. I would be surprised if Cisco were not all over
this at some point in the next year or two. </div>

<div>I am curious to find out what others have done in regards
to<br>leveraging emergency responder and more specifically working
through<br>the process for transmitting your ALI info.<br><br>Personally I
have not had a lot of luck in determing the process from <br>my service
provider.<br><br>Like many who have CallManager we have PRI's coming into
a main<br>office, we have satellite offices in many different cities
with<br>different PSAP's and such. The users have phone numbers tied
to a DID <br>range tied to the PRI's and well 911 is an issue.<br><br>We
plan to leverage ER to identify phones in those offices and tie<br>them to
an ELIN associated with the address of that office. Nothing<br>too
detailed or granular. <br><br>The primary issue at this point is getting
info to the service<br>provider I guess. I don't think we are
suppose to deal with<br>individual PSAP's. My understanding is we
are suppose to send info to<br>the service provider of our PRI's, who is
suppose to send the info or <br>pass it on to PSAPs I guess.<br><br>Just
looking to hear what others have done regarding this process,
the<br>trials and tribulations if you will of figuring out this aspect of
the<br>whole thing, it does seem to be the most important component of
<br>rolling out
ER.<br><br>later<br><br> </div></span></blockquote><br>_______________________________________________<br>cisco-voip
