Question

我正在使用delphi 6中的Async Professional库对Avaya Ip Office呼叫中心执行tapi呼叫。

我已成功通过vcl组件执行传出内部调用（ApdTapiDevice1，ApdTapiStatus1，ApdComPort1）。

我想检测来电的来电号码。这可能吗？

提前致谢！

TApdTapiDevice有OnTapiCallerID个事件可以挂钩以获取CallerID字符串和CallerIDName。

它还提供CopyCallInfo方法，该方法提供ITCallInfo接口（请参阅：MSDN ITCallInfo）。这会公开一个方法get_CallInfo（MSDN : get_CallInfo），它可以检索由CALLINFO_STRING枚举（MSDN : CALLINFO_STRING）枚举的信息字符串。

TApdVoIP组件还提供CallInfo属性，其中包含有关呼叫的扩展记录。

TApdVoIPCallInfo = record
    InfoAvailable : Boolean;       { True if we get the info, False if the }
                                   { ITCallInfo interface isn't available  }
    { string type fields }
    CallerIDName,                  { the name of the caller }
    CallerIDNumber,                { the number of the caller }
    CalledIDName,                  { the name of the called location }
    CalledIDNumber,                { the number of the called location }
    ConnectedIDName,               { the name of the connected location }
    ConnectedIDNumber,             { the number of the connected location }
    CalledPartyFriendlyName,       { the called party friendly name }
    Comment,                       { a comment about the call provided by the originator }
    DisplayableAddress,            { a displayable version of the called or calling address }
    CallingPartyID : string;       { the identifier of the calling party }
    { DWORD types }
    MediaTypesAvailable,           { the media types available on the call (TAPIMEDIATYPE_*) }
    CallerIDAddressType,           { the address types (LINEADDRESSTYPE_*) }
    CalledIDAddressType,
    ConnectedIDAddressType,
    Origin,                        { the origin of the call (LINECALLORIGIN_*) }
    Reason,                        { the reason for the call (LINECALLREASON_*) }
    MinRate,                       { the minimun data rate in bps }
    MaxRate,                       { the maximum data rate in bps }
    Rate : DWORD;                  { the current rate of the call in bps }
  end;

如果您正在使用AsyncPro进行认真的开发，那么保留copy of the reference manual handy非常值得。
