Enable or Disable Call Waiting for Cloud Voice App UC Clients
Call waiting lets an extension take a new incoming call while the user is already on an active one. As an administrator, you can turn the feature on or off for an extension’s Cloud Voice App (the user’s unified communications, or UC, clients), and your choice is pushed automatically to that user’s mobile, desktop, and web apps.
Requirements
Section titled “Requirements”Before you configure call waiting, confirm that the PBX (Private Branch Exchange, the phone system) and the user’s apps meet these minimum versions.

Result
Section titled “Result”The setting syncs to the user’s Cloud Voice App and takes effect right away. How the system handles a second incoming call depends on the setting:
- Call waiting off: When a second call arrives during an active call, the system plays “The extension you dialed {extension_number} is busy now.” and then drops the new call.
- Call waiting on: When a second call arrives during an active call, the system plays “Please hold on, the extension you dialed {extension_number} is busy now.”, and the user hears a tone signaling the waiting call.
