<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>
