911 Notification support
The SIP Application Module supports Instant Message notifications to
a specified On-Site Notification (OSN) location whenever a user makes
a call to an emergency number such as 911. The software provides this
service using the same mechanism that allows users to push web
pages and/or email links back to the originator of a call. In order to do
this, administrators set up (at the Personal Agent) an emergency
subscriber for each OSN location and a private telephony route to map
the emergency number to this subscriber. Since telephony routes are
only unique within a subdomain, you cannot have more than one OSN
location for each subdomain.
For each new emergency subscriber that the administrator creates,
there must be both
• an emergency number to route to the Public Safety Answering Point
(PSAP)
• a SIP subscriber assigned to the OSN location that is to receive the
notification.
Each OSN location must have a specific subscriber assigned, such
as sip:[e-mail].
