Syntax
<Result> = tapiLineDial(<Line to Use> , <Number to dial> [, <Procedure name> [, <Duration> [, <Custom parameter>]]])
<Result>: Integer
  • Identifier of call dialed.
  • 0 if an error occurred. The error details are returned by ErrorInfo.
<Line to Use>: Character string
Line or device to use.

Reminder: The list of telephony devices is returned by tapiDeviceList.
<Number to dial>: Character string (with quotes)
Phone number to dial.
<Procedure name>: Optional character string (with or without quotes)
Name of WLanguage procedure used to manage the progress of dialing. This procedure has the following format:
PROCEDURE <Procedure name>(<Line status>, <Parameter>)

The first procedure parameter (<Line status>) is an integer that can take the following values:
tapiLineBusyThe line is currently busy.
tapiLineConnectedThe line is connected.
tapiLineDialingDialing in progress.
Note: If TAPI 3.1 technology is used, this constant is no longer returned.
tapiLineDialToneThe line gets a dial tone.
tapiLineDisconnectedThe correspondent has hung up.
tapiLineProceedingThe call is dialed: searching for the correspondent.
tapiLineRingBackRinging in progress.
The second procedure parameter (<Parameter>) is the custom parameter passed to tapiLineDial.
Caution: this procedure must contain no call to the debugger (no breakpoint, no STOP keyword, no auto-stop expression, ...).
<Duration>: Optional integer or optional Duration
Maximum wait duration (in seconds). Beyond this duration, the function assumes there is no response (no one picked up). This parameter can correspond to:
  • an integer corresponding to the number of seconds,
  • a Duration variable,
  • Versions 23 and later
    the direct indication of duration (1 s or 10 ms for example).
    New in version 23
    the direct indication of duration (1 s or 10 ms for example).
    the direct indication of duration (1 s or 10 ms for example).
This parameter corresponds to 15 seconds by default.
<Custom parameter>: Any type, optional

Remarks

Differences between tapiDial and tapiLineDial

  • tapiDial is used in a context of a single outgoing call. The identifier of this call is not available.
  • tapiLineDial is used in a context where several simultaneous calls can be found. tapiLineDial returns the call identifier. Therefore, it can be easily handled (to transfer a call for example).

Limitation

tapiLineDial cannot be called in the procedure for call detection (defined by tapiListen).
