Tapi3 (register incomming calls how???) RRS feed

  • Question

  • This is the code I'm using (https://www.codeproject.com/Articles/10994/TAPI-Application-development-using-C-NET)

    We are using the CAESAR CTI Client for our CallCenter. 
    I don't get any Event, when somebody is calling to me.

    When I start the program, I have the oppertunity to select one out of 64 Lines

    I get the Lines: "TM Line103" - "TM Line131" and "Trunk 1" - "Trunk 32"

    We have registered every line. After each registration we tested with a call wehether something happened, but no call results in an event. 

    Pleas! I need your help!

  • Hi  Maxi_Bergbauer,

    As far as I know, TAPI, standing for the Telephony Application-Programming Interface, is the mechanism by which computers can respond to phone calls.

    TAPI is not supported from managed code.

    You can call TAPI 3.x (Tapi3.dll) functionality from unmanaged code. Create an unmanaged DLL that calls TAPI 3.x functionality, and then call the unmanaged DLL from managed code.

    I found the following post have a similar issue with you. I hope it will help you.

    Tapi 3 and C# no Event triggering after first call:

    The following two forums may can give your some suitable help.

    As far as I know, this is currently the only existing forum dedicated to TAPI discussions.

  • We have the same problems with the Ceasar CTI and Tapi. No events are coming from the tapi driver on calls.

    @Maxi: did you find a solution?
