Using in-call controls

After using Zoom Phone for making or receiving calls, you’ll have access to in-call controls like recording the call, adding another person to the call, or transferring the call. 

During a call, you can use the following in-call controls. These controls are the same across Windows, macOS, Zoom Web App, Android, and iOS.


This article covers:


Mute / Unmute

Mute or unmute your mic.


Display a dial pad to enter numbers during the call. For example, the dial pad allows you to select an option during an interactive answering machine or to enter an extension number.


Open audio settings and change the volume of your speaker or mic.

Add Call

Display a dial pad to enter a number and add another person to the call (three-way call). Each person will remain on a separate line. Click or tap their name or number to switch between each person.

To merge the calls and enable three-way calling, click or tap the merge icon and select the person or number to merge with.
Note: While in a 3-way call, if a call participant leaves the call, the call will continue for the remaining 2 phone users.

Hold / Unhold

Place the call on hold or resume the call. The receiving party will hear music while they’re on hold. You can customize your hold music in the Zoom web portal. While the call is on hold, you can use call flip to switch the call to another device (Zoom desktop app, mobile client, or desk phone).


Transfer the call to another number. You can also transfer the call to voicemail.

End call


The End call button immediately terminates the call. Once the call has ended, your Zoom client status no longer says On a call and the call timer is no longer displayed.


Start or stop recording the call. You may hear an audio prompt notifying both parties that the call will be recorded (the audio prompt can be disabled by the admin). Play and manage your recordings using the desktop client, mobile app, or web portal. Admins can access your ad hoc call recordings if the ad hoc call recording was made during an inbound or outbound call queue call.

You can also start and stop an ad-hoc or automatic call recording by using a DTMF code.

The following scenarios affect call recordings:

Stop Recording

If your admin enabled the ability for you to stop/resume automatic call recordings, you can click Stop Recording to stop the automatic recording. Optionally, you can click Record to resume recording.

Note: If you resume the recording, you will record to the same recording file. Zoom will not create a separate recording file. As a result, you will see a single recording file/entry when you or an admin views recordings. View recordings in the web portal to see the timestamps of when the recording was stopped and resumed.


Elevate the Zoom Phone call to a Zoom meeting.


Access the following controls.

Note: In More, the only features supported on Zoom Web App are park and minimize.

Call encryption and quality icons

Click or tap the three icons to view the encryption and quality status of your current call.

If you're experiencing low call quality, learn about phone statistics and recommended values.

Down arrow icon

Click or tap the down arrow beside the caller ID to view the participants in the call. This will also display the direct phone number you used to make or receive the call. If you made or received the call using a company number, you will also see your extension number.

Note: You can also view your company number and extension at any time using the caller ID drop-down menu below the dial pad or in your web, Zoom Web App, or client/app settings.
