Example: Defining a disconnect detection tone

Custom trunk disconnect detection tones are used in installations where a PBX sits between the central office and Strata CS, and where the PBX does not provide a fast busy tone to indicate trunk hangup.

The keys in the next table are DWORD values that define a disconnect tone with the following characteristics:

nA Dual Tone Frequency of 400Hz – 450 Hz (that is, 425 +/- 25)

nOn between 460ms – 500ms (that is, 480ms +/- 20ms)

nOff between 440ms – 480ms (that is, 460ms +/- 20ms)

nCadence must repeat 2 times

nCadence begins on the leading edge of the tone

Disabling Dialogic devices ______________________________

By default Strata CS allocates and opens all Dialogic devices that are present on the Server for itself. If you do not want Strata CS to allocate all of the available devices (for example, if you are connecting fewer lines to a Dialogic board than the board can support), use the procedure described later in this section to disable the Dialogic devices.

You might need to disable Dialogic devices for any of the following reasons:

nTo allow non-Strata CS applications to run on the Strata CS Server
