DND on Rainbow causing issues with Group Hunts on the OXO

Hi Team,

Is there a design flaw with Rainbow when a Rainbow subscriber member is added to a group hunt in the OXO and the Rainbow member activates DND and activates in settings/Telephony/ "DO NOTDISTURB" MODE is tick for "Ignore Interent VoIP calls while the ststaus is "Do not disturb" it forces all calls to the group hunt to go to vmail 500?
