IVR Plug-in licensing
IVR Plug-ins are licensed at runtime and count against your station licenses. Your
system may be configured to support an unlimited number of Plug-ins, but each
simultaneous call to an IVR Plug-in will consume one station license for the
duration of the call.
For example, if you have a system with 16 station licenses, and 15 of those
stations are assigned to users, you have one free station license that can be applied
to calling an IVR Plug-in. If one person makes a call to a Plug-in, and during the
call another user makes a call to the same or a different IVR Plug-in, at that point
the caller hears a message that the extension is not available, and an error is
logged to the Strata CS Server’s Windows NT Event Log saying that the license
count has been exceeded.
The Device Status API
The Device Status API provides functions that allow an application to monitor the
status of all devices (stations and trunks) on a Strata CS Server. The application
can obtain the device name, number, hook state, current activity, and extensions
for each device on the system. Each extension can be examined for the extension
number, the user’s name, and whether the extension is in a Do Not Disturb
personal status. Using these functions, the application could:
n Monitor current users on the system and maintain a call log in a format
customized for your special needs.
n Obtain a current list of users permanently assigned to a station.
n Obtain the name of a user currently logged in at a station.
n Identify the trunk to which a station is connected.
All Device Status information is read-only. The API can be used in combination
with the IVR Plug-in API to provide IVR applications with device information.
The Device Status sample program
The Device Status sample program is a Visual Basic project for a simple device
monitor that displays a constantly updated list of status reports on each device in
the system. Programmers can use this sample program as a starting point for their
own applications, expanding and customizing it as desired. It requires no
hardware or software beyond what is already required for the Strata CS Server
and Visual Basic.
