Prolog information
Avaya provides many URI formats that third-party applications can use. Avaya supports the following verbs as part of the URI:
  • Audio calls
  • Video calls
  • Instant messaging
  • Configuration
By using Avaya URIs, third-party applications can direct Avaya Workplace Client to:
  • Create an audio call.
  • Create a video call.
  • Create a conference call.
  • Create a new or open an existing conversation.
  • Update the automatic configuration URL.
Note:
Avaya Workplace Client for Windows also supports the tel and CallTo URIs. For example, tel:+16135959132 and CallTo:+16135959132. If the user clicks on these URIs in a browser or elsewhere, the call is dialed immediately after choosing the default application.
Avaya URIs have the following format with optional parameters: avaya://verb?address&parm1=value1&parm2.

All platforms do not support all Avaya URI parameters. If you provide an unsupported parameter within the Avaya URI, Avaya Workplace Client ignores the parameter but continues to invoke the verb. The verb invocation is only one-way because Avaya Workplace Client does not provide status updates to the third-party application.
Note:
Android does not detect any custom URIs, such as non-global URIs, in emails and text messages. On Android, you must create custom URIs as HTML or web pages so that the URIs are clickable, and Avaya Workplace Client for Android initiates the desired action.
