StartAudioCallButton Control

  • 아티클

Use the StartAudioCallButton control in Microsoft Lync 2010 Control applications to enable the user to open a Microsoft Lync 2010 conversation window and start a voice conversation between the user who activated the control, and another user. StartAudioCallButton is a split-button control. When clicked, the left side of the split button places a call to the default number that is associated with the contact. The right side of the control exposes a menu of calling options, such as Lync Call, Work, and Voice Mail.

Property

Description

DisplayName

Gets the display name of the currently signed-in user.

Source

Gets or sets the contact to use. Valid types include Contact and DistributionGroup objects, and String.

  • If the value is a string which does not contain the sip: or tel: prefix, the control will perform a search, using the string specified as a search criteria, and will load the first contact in the result set matching the specified string. This behavior is not deterministic, and yields the slowest performance.

  • If the value is a SIP URI string qualified by the sip: or tel: prefix, the contact will be loaded using an exact match of the specified URI. This behavior is deterministic, and yields better performance.

  • If the value is a Contact or DistributionGroup object, it will be used without changes. This behavior is deterministic, and yields the best performance.

ContextualInformation

Gets or sets a data structure which contains information used to customize the information that accompanies messages. For more information about the use of contextual information, see Lync Extensibility API Contextual Conversations (Lync 2010 SDK).

Model

Reserved for internal use. This property may appear in XAML text when editing templates. To preserve control functionality it should remain static.

Code Example

The following example can be used for Microsoft Silverlight and Microsoft Windows Presentation Foundation (WPF) application development.

<StackPanel>
  <controls:StartAudioCallButton Source="sip:elise@contoso.com"/>
