ISDN Card and Headset

Page Index

Trustinfo CTI Client in combination with ISDN card and Headset
On this side is briefly summarised which settings are to be carried out if you want to use the application in combinationwith an ISDN card and Headset.
Configurations
To be able to phone by ISDN card and Headset, there are the following basic configurations:
  • ISDN-Card + Soundcard + Headset
    This is the cheapest combination. However, in the quality of the Headsets should not be saved. Cheap ISDN cards are likewise to be avoided, because this partial do not support consultation and call waiting. The Trustinfo CTI Client was tested with Fritz AVM! Card.
  • ISDN-Card + USB-Sound-Adapter + Headset
    This combination is comparable in principle with first, however, has the advantage that the USB sound adaptor is administered as an additional sound device in the PC and therefore no conflicts with other applications are to be expected which access the sound card and change, perhaps, the mixer settings.
    This variant was tested with AVM Fritz!card and Plantronics Headset "DSP 100".
  • ISDN-Card with direct Headset connector + Headset
    The first both variants have the disadvantage that system-based small speech delays and echoes appear. By using of an ISDN card with direct Headset connection these effects do not appear, because the speech data are processed without delay on the card. The speech quality is identical with an ISDN phone. Disadvantage: relatively cost-intensely.

Configuration of the ISDN card in the CTI Client

How to configure of the ISDN card:

  • [Options > PhoneDialog (TAPI Device) > Select > local CAPI > CAPI-TSP for SoundCard]
    Click for adding on [Select TAPI Device].
  • While running the the first configuration a dialog appears to the enter the MSNs. The driver can manage up to 6 MSNs.
    If you have entered several MSNs, one more dialog appears to select single MSNs and assign to them an alias name.
  • Now, the line "CAPI-TSP for Sound Card" should be visible in the Device dialog.
    • Close the device dialog with [OK].
