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.

Examples:

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. Then the dial commands (phone numbers) are sent directly to the phone.
=> see: Special Devices

"Standard" means no special device. In this case your phone is called from the Asterisk PBX first.

  • Your name: The calls are signalled with this name to the called party.
  • Context: Context for "Originate" and other commands like "Redirect". A Context is a section in extensions.conf.
  • Use other Cannel: You can use this option then call setup (originate) needs to be executed to another channel. Default: Off
    • Application example "Multi Device with PJSIP": If you enter "local/xxx" here. Where xxx stands for the extension number (similar to the entry under Channel), then all phones of the extension should ring when dialing. The connection will then be established with the telephone you pick up.
      • Special case: In connection with FreePBX 15 "local/xxx@from-internal" should be used.

CallerID: Settings to display the caller information on your phone and the called party. See also:CallerID-Patch

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

Write Log file: This option is move to [Server Settings> Log].


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.
