Which feature allows multiple users to be connected during a call in Webex Calling?

The feature that allows multiple users to be connected during a call in Webex Calling is conference calling. This functionality enables participants to join a single call, facilitating group discussions and meetings without the need for separate calls for each individual. Conference calling signifies the system's ability to manage multiple audio streams simultaneously, allowing all participants to hear and speak to one another effectively. This is particularly useful in business scenarios where collaboration and communication are key.

Call park, while useful for placing a call on hold so other users can retrieve it, does not inherently connect multiple users in a conference. Call waiting allows a user to manage incoming calls while already on a call, but again, it does not create a multi-user call environment. VoIP integration refers to the technology that allows voice calls via the internet but does not specifically address connecting multiple users in a conference call scenario. Hence, conference calling is the clear choice for enabling multiple connections during a single call.
