Handling mass incoming calls

• QueueHold callers in line and keep ringing your team until someone answers.
• Queue priorityGive some callers a higher priority so they're answered first in a queue.
• Queue callbackLet callers leave their number instead of waiting, and call them back when a user is free.
• Call parkingPut a call on hold in a numbered slot so anyone on the team can pick it up.
• Ring groupRing several users at once or in turn, and send the call elsewhere if nobody answers.
