StrataLink Functions
StrataLink has three basic functions. It:
◆ Accepts events from the telephone, applies filtering rules and conditions and causes
actions to take place in the application.
◆ Provides for outbound calling and call control from the application.
◆ Provides tools for testing the interface and debugging or monitoring the call events.
Processes Telephone Events
Using Windows TAPI, StrataLink accepts the Strata DK commands and provides a selection
of "Actions" based upon call events, called Triggers. Each Trigger can have one or more
conditions applied to it to control how, when, or if the Action is to be performed. Each
Action has a limited set of parameters that can be changed to customise the application for
the user. A list of Trigger events can be selected for the Action desired.
Provides Outbound Calling and Call Control
The Computer Telephony Software creates events for controlling the telephone. The events
are controlled using DDE exchanges originating from the application and received by
StrataLink. In some programs, the application software must be configured for this
operation.
Test, Debugs, and Monitors
StrataLink provides several important testing and debugging functions. These tools enable
the installer to verify whether the link is functional and by using the TAPI link, to view the
details of the information being passed. Without these tools, the troubleshooting or verifying
operation is reduced to guessing.
