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:guarddeskA@nortelnetworks.com.
