The AddToConference adds the specified call appearance to
this conference call.
Function AddToConference(ConsultCall As TAPICall) As Boolean
If the method succeeds, the return TRUE, otherwise return FALSE. Use ErrCode property to get the error code if return FALSE.
Using ConfRelatedCalls, you can obtain a list of call that are part of the same conference call as the specified call. The specified call is either a conference call or a participant call in a conference call. An individual participating call can be used later to remove that party from the conference call using RemoveFromConference.
Note All calls that are part of a conference must exist on the same open line.
The call states of the calls participating in a conference are not independent. For example, when dropping a conference call, all participating calls can automatically become idle. An application should consult the line's device capabilities to determine what form of conference removal is available. The application should track the OnCallStateChange events to determine what happened to the calls involved.
The conference call is established either by SetupConference
or CompleteTransfer. The call added to
a conference is typically established using SetupConference
or PrepareAddToConference. Some switches
can allow adding arbitrary calls to the conference, and such a call can have
been set up using MakeCall and be on (hard) hold.
The application can examine the Address_Capability_Flag member of the ILineCaps
to determine the permitted operations.
