TAPI Line Configuration

In first step you have to configure the Asterisk Server parameters.

TAPI Line Configuration - Device Parameter

Now you have to enter the parameters in section "Asterisk TAPI Device". The dialog image shows an example for a SIP phone with extension "201".

Channel: Your phone identifier within the telephone system.


Your phone number: This is used as "callerID" and optionally for call detection.

Use this extension number for call detection too:This option may help to assing calls to your ZAP-channel. Default: Off

Parameters for TAPI controlled call setup

Special Device:

  • If you use one of the listed phones, you can select this. The dialing commands are then sent directly to the telephone.
  • "Standard" means no special device. In this case your phone is called from the Asterisk PBX first.
  • The possibilities of "TAPI-controlled call setup" are relatively varied and in need of explanation. Therefore, the parameters are described on the following page:
  • Functions such as "Answer" and "Hold" are usually also supported for selectable IP telephones.



If these settings are done the TAPI driver should work now.

Special Lines for "Hint" display

Example: With *280 the day/night-service can be switched in the system.

If you set Channel=*280, this TAPI-Line can be used to display an active night service.  

The TAPI driver monitors the Manager Interface for ExtensionStatus events with "Exten: *280" and then sends a special LINE_ADDRESSSTATE event (LINEADDRESSSTATE_FORWARD + LINEADDRESSSTATE_DEVSPECIFIC). When the program starts, the command "core show hints" queries the Hint states of the system. Example AMI sequence.
If the TAPI application then queries lineGetAddressStatus(), the parameter LINEADDRESSSTATUS::dwDevSpecificSize contains, for example, "UserCustomInfo: ON" or "UserCustomInfo:" in the "off" state.

In the CTI Client you can assign such a Line to a speed dial key with: Type=dial programming code, Name=Night service, Phonenumber=*280. An active night service should then be signaled with a blue LED. Clicking the speed dial button dials the *280 via the PhoneDialog line and thus switches the day/night service.
