About this task
Use this procedure to make a voice or video call using the alphanumeric Uniform Resource Identifier (URI). For example, you can use the alphanumeric URI to call an external user, such as a Skype for Business user, using 123john@telenor.com.
Note:
Avaya Workplace Client for Windows also supports the tel and CallTo URIs. For example, tel:+16135959132 and CallTo:+16135959132. If you click on these URIs in a browser or elsewhere, the call is dialed immediately after you choose the default application.
