ThbTapiCall.Info
Unit: hbTapi
 

This property is designed to encapsulate the TAPI LINECALLINFO structure. The most often used value are accessable directly at the call level like call.MediaMode. So the Info property is needed only in special cases. You are able to read all values of LINECALLINFO defined in TAPI below version 3.0. Do do so write e.g. BearerMode instead of dwBearerMode. The LINECALLINFO structure is accessable too. Use the property ThbTapiCall.LINECALLINFO, that is a pointer to the LINECALLINFO structure.

Example

Label1.Caption := Format('BearerMode= %x', [Call.Info.BearerMode]);

    -- or with the TAPI structure --

Label1.Caption := Format('BearerMode= %x', [Call.LINECALLINFO^.dwBearerMode]);
