In the case of a notification action that is in the form of an e-mail, SMS, or page, and a dial notification to a large number of users, what is the sequence of notification events?
A. The dial engine uses a scalable, multi-threaded dial-pool implementation for dialing out to users. Ports from the available dial pools are used by the currently executing policy notification/invite actions. If there are fewer dial ports available than what is needed, the other policy actions are put in a waiting state until more ports become available. A call is considered successful when the call recipient authenticates. If there is no authentication, the system moves to the next dial preference that is listed in the Communications Preferences tab for the user in the user profile until either the call is successful or every number has been tried by the system. For detailed information, see the “Allocating Dial Ports for the Dial-In/Invite and Notification Features” section on page 6-28.
