CallFeatureService MakeNoHoldConference Method

Start No Hold Conference for active call, or add new participant to existing conference.

Namespace: Avaya.ClientServices
Assembly: AvayaClientServices (in AvayaClientServices.dll) Version: 592.1.30.0
Syntax
C#
Copy

    public void MakeNoHoldConference(
    	string destination,
    	CallFeatureServiceFeatureCompletionHandler completionHandler
    )

#### Parameters

destination
  Type: System
  String
  Network address of the person who is being added to the conference call.
completionHandler
  Type: Avaya.ClientServices
  CallFeatureService
  FeatureCompletionHandler
  Completion handler instance that receives the result of the operation. If not provided, failure feedback cannot be provided.

Remarks
No Hold Conference feature button allows a user to set up a conference call without interrupting the current conversation. The called party is automatically added to the conference as soon as they answer. Successful completionHandler is invoked after invited party answered, or the feature was canceled. Current active call will be transformed into the conference. The number dialed by the user is sent as a message and not as tone so that the digits are not heard by any party on the call. So No Hold Conference button should be used if it's important that no tones are heard by participants, and/or remote user should not be held. In other cases AddParticipantFromCall/AddParticipant methods of Conference interface should be used. No Hold Conference is Avaya Communication Manager feature, which is not available in other environments.
