When enabling DND on the Songoma Connect client using iphone11 Pro on ios 13.7 the phone will still vibrate for a brief second and then reject the call. This is regardless if the extension is direct dialed or in a ring group.
Also unable to stop vibrate whether DND is enable or disabled. iPhone ringer is turned on and silent is off and still Mobile Connect vibrate accompanies ring when DND is disabled and no ringtone when enabled.
