Installing on Dialogic Systems

Dialogic cards supported

The following Dialogic media cards have been tested to work with INS:

Diva Analog Diva UM-Analog Diva 4BRI and Diva UM-4BRI-8 Diva BRI-2 and Diva UM-BRI-2

The Diva UM-Analog is about US$600 brand new from a number of large online retailers (please see the Communication Devices page), and many cards can be purchased second-hand on Ebay for as little as $200 – just search for “Diva” on


Installing Dialogic Diva Software

The free Dialogic® Diva® System Release 8.5WIN (or later) software should be used with INS.

Dialogic System Release software can be downloaded for free from:  (18MB)
Then just follow the instructions of the installer.


Please select the following options when installing the
Dialogic® Diva® System Release:


Make sure to enable the TAPI option



The Diva cards come out of the box with a rollover feature. No matter what port you dial into, the call will always ring on the
first available line. You can override this.


For better voice quality we recommend to set the "Wave:Performance Options" to "Minimum Delay"





Voice File Format supported
When using Dialogic TAPI drivers all sound files must be in format: CCITT u-LAW 8kHZ, 8 bit, Mono. That is the only format which the Dialogic Diva TAPI driver accepts.
To convert the files you may have recorded before (and also the files in the C:\INS\assorted directory), you may use the windows Sndrec32.exe or a similar tool.
Be especially aware that the Dialogc cards do not accept any noise recorded with the voice files. Noise while recording your voice files makes the final playback quality unbearable bad. Therefore always use a software to filter any noise after recording.




With the above steps the TAPI and WAVE driver used by INS should be installed and properly working.
If you experience problems, please refer to the manual installation guides below
