When you are in a Webex meeting and receive a call in Jabber the ringtone is not muted even though the "mute all sounds during a meeting" option is enabled. This causes interruptions during meetings whenever new calls are received. Currently it seems the only ways to mute the ringtone for incoming calls are to manually set Jabber presence to Do Not Disturb or by completely disabling the ringtone (a new option in 12.8). It would be helpful if Jabber had the ability to truly mute all sounds including the ringtone while a user is in a Webex meeting. Since Jabber is aware of Webex meetings and changes its presence status to "In a Webex call" (orange) while in an active Webex meeting, it seems like this should be possible.
