VCC CC Admin can Activate or Inactivate queues from Admin UI. Inactivated queues will retain all the reporting and call recordings, but cannot receive calls. Inactivated queues will not be waited during VCC restart.
VCC queue voicemail calls are diversion inhibited, i.e. they will not be diverted to an agent's personal voicemail box even if s/he did not answer the call. Forcing an agent to Unavailable for Not Responding rule also applies to voicemail calls.
