CallEmbed asked Element Call to send a call-start notification for every non-DM call. In persistent voice channels and space rooms it carries an @room mention: every member got a highlighted ping (and phone push) whenever a moderator or admin joined first, and other clients showed it as a missed call. Now only rooms that can ring (isRingableRoom: DMs and invite-only groups outside a space) get ring/notification; everything else passes sendNotificationType=none (element-call-embedded 0.25.0-lotus.23). Verified with a local build of the fork: an admin joining the Voice Lounge sends none, and Bob gets no new notification (before: +1 highlighted).
