tapiHangUp()
END PROCÉDURE TestLineStatus(ValueLineStatus is int)
SWITCH ValueLineStatus
CASE tapiLineBusy: Message("The line is busy")
CASE tapiLineConnected: Message("OK, connected")
CASE tapiLineDialing: Message("Dialing in progress")

END Syntax
<Result> = tapiDial(<Number to dial> [, <WLanguage procedure> [, <Duration> [, <Custom parameter>]]])
<Result>: Boolean - True if the line is opened: you can pick up the receiver and talk,
- False otherwise. To get more details on the error, use tapiError.
<Number to dial>: Character string Phone number to dial. To specify a prefix (0 for an external line for example), use a comma in the number. For example: "0,0467789066". <WLanguage procedure>: Optional procedure name Name of WLanguage procedure used to manage the progress of dialing. For more details on this procedure, see Parameters of the procedure used by tapiDial. Caution: This procedure must not contain any call to the debugger (no breakpoint, no STOP keyword, no auto-stop expression, etc.). <Duration>: Optional integer or optional Duration Maximum wait duration (in seconds). When this timeout is exceeded, the function assumes that there is no response (nobody picked up).
This parameter can be: - an integer corresponding to the number of seconds,
- a Duration variable,
- the duration in a readable format (e.g., 1 s or 10 ms).
<Custom parameter>: Any type, optional Parameter passed to the WLanguage procedure. Remarks Differences between tapiDial and tapiLineDial - tapiDial is used in the context of a single outgoing call. The identifier of this call is not available.
- tapiLineDial is used in a context where there may be several simultaneous calls. tapiLineDial returns the call identifier. Therefore, it can be easily handled (to transfer a call for example).
Limitation tapiDial cannot be called in the procedure for call detection (defined by tapiListen). Required configuration Telephony functions use TAPI 2.0 technology and/or TAPI 3.1 technology. These technologies can be used on all systems.
