Disabling 'Call phone' in Gmail
If you do not wish to use or see the Call phone feature in your Gmail chat list, you can disable it. To do so:
- In the upper right-hand corner of Gmail, click on the gear icon and then click on Mail settings.
- Click on the Chat tab.
- In the Call Phone section, click on Disable outbound voice calling.
- Click on Save Changes.
The above steps only disable outbound calling in Gmail. If you have enabled Google Chat as a forwarding phone in Google Voice, you must disable it separately.
