Two thoughts.<div><br></div><div>1. the legal Disclaimer with a big sticker on the phone that says DO NOT USE 911.</div><div><br></div><div>2. 911 enable has a great setup. they use sip trunks and route the calls to the correct PSAP(nationwide). they have an application that will ask the phone user (SOHO) for location (address) and will route the call correctly to the right PSAP with the correct address. I know of a very large customer who scrapped CER for these added features. But it is more expensive then CER.</div>

<p class="MsoNormal"><span style="font-size:10.0pt;color:#1F497D">To add something to the mix on this, what are your thoughts on
having remote users who have IP Phones at home, VPN tunnel to head office
and are registered to the Head Office UCM. When they dial 911, the call
would come from the Head Office rather than the users homes location. They
may have their own phone setup – as most people invariably do – but
if they are at their desk then they will automatically use their IP Phone. Bearing
in mind this is only a connection with an ASA to the Main Site – so no SRST
etc – what are peoples thoughts here?</span></p>

<p class="MsoNormal">Group,<br>
<br>
We have several sites which are remote from the main campus but are<br>
"local" in as much as they are located within Qwest's Tucson rate<br>
center. The ones that are equipped with Voice over IP get all of<br>
their connectivity and DID extension numbers from the CallManager<br>
clusters on campus. The CallManager clusters are equipped with Cisco<br>
Emergency Responders so that all 911 calls are routed to the proper<br>
PSAPs with the proper emergency response address as set up in the<br>
Intrado database.<br>
<br>
When everything is working properly, all 911 calls go where they're<br>
supposed to go and have the correct response location in the PSAP's<br>
automatic location identifier field.<br>
<br>
A remote site user asked "Will I be able to call 911 from my location<br>
with my VoIP phone when the WAN is down?" and our answer is
"No."<br>
<br>
So the question for the group: Is it your custom to provide facilities<br>
(phone line, gateway interface interface card, DSPs, SRST software,<br>
etc.) solely to allow access to 911 in the event of a WAN failure?<br>
<br>
Is the possibility that the WAN will be broken at the exact time<br>
someone needs emergency help (and can't find a cell phone) great<br>
enough to justify the additional facilities?<br>
<br>
Thanks in advance.<br>
