Overflow Call Queue Overview | RingCentral

« Go Back


SummaryThis article gives the overview of the Overflow Call Queue feature, its requirements, availability and provides the links for configuring Call Queue settings.

The Call Queue Overflow feature allows the other incoming calls to be routed to another Call Queue where other Users can assist them; the rest of the unanswered calls will be routed to voicemail.

Key aspects include:

•   Queue Trigger - If the primary queue lines are all busy, overflow calls can go to the extended queue allowing more calls to be answered. The primary call queue should be configured using the Rotating and In fixed order call sequence.
•   Call Flow Behavior - Overflow management follows the settings for the original Call Queue. Set-up policies for the primary queue will persist including: Call Handling Timers, Greetings, Voicemail, After Hours Settings. Calls to a Call Queue with overflow are handled as an extended single Call Queue. The members in the overflow queue will always be called on Rotation sequence.
•   Call Flow Setup - Settings are configured in the online account with an additional UI presented. Feature can be enabled/disabled as needed once created.

IMPORTANT: The Simultaneous protocol is not supported in the meantime. Small delays in ringing each User's phone would likely cause issues such as continuous ringing for some users after the call is answered.



This feature is available to RingCentral Office Premium and Office Ultimate plan users.
