ASAI and Supported Applications
■Initiate, terminate, and control (hold, reconnect, transfer, conference) calls at the user’s phone
■Invoke ECS features [that is, Call Forwarding, Send All Calls (SAC)] on behalf of the phone
■Provide messaging services that integrate the Message Waiting Indicator at the user’s phone
Incoming Call Identification
The Incoming Call Identification (ICI) application displays the calling party name and telephone number on the user’s data terminal. Based on the displayed information, the user can decide whether to answer the call or send the call to coverage.
A sample scenario for the Incoming Call Identification application is as follows:
1.The application uses the Domain Control capability to monitor all calls originated and received by or delivered to users’ phone sets.
2.When an incoming call is delivered to a user’s phone, the ECS sends an Alerting Event Report containing the call’s CPN/BN and dialed number (implies redirection if different from the alerting phone).
3.The application displays, at the user’s data terminal, the information
contained in the Event Report as the call rings the user’s phone. When CPN/BN is available, the application searches its own database3 (for example, corporate directory or customers’ database) of names and telephone numbers, so that the calling party name is also displayed on the user’s terminal.
4.Based on the information displayed at the data terminal, the user can answer the call or invoke the SAC feature from either the data terminal or the telephone set. Alternately, the application may request Redirect Call based on the information obtained.
Phone Management and Directory Services
A Phone Management and Directory Services application may allow telephone users to:
■Originate, answer, and manipulate calls at a station by using hold, transfer, reconnect, answer, conference, and drop
■Request to make a call using the called party name
■Create a personal directory list (the user might define his or her own directory to be used by the application when searching for a telephone number to be included in call request)
3.The user may define the personal directory database to be used by the application.
