Webex allows users to mute notifications, for direct calls when in meetings. However, this only works if a user joined a Webex Meeting, using Webex app. If the user joins a Zoom, GoToMeeting, or other non-Webex meetings, the mute-notifications do not work.
Even if one joins the meeting using the Webex Meetings app, or is on a phone call, using a connected phone, the Webex app does NOT recognize it and mute notifications.
