P-Series Cloud PBX
Set up: Ring group 6300 with failover to ring group 6301 after 30 seconds ring timeout.
If a call goes unanswered in ring group 6300 but is answered in ring group 6301 the phones in ring group 6300 still show a missed call notification.
This is not the case in the S-Series appliance. Please add a feature where the missed call notification is not displayed if the call is answered elsewhere.
