Virtual Slots
  • 14 Subscriber / Interface
    (per SIS Instance)
  • 4 Subscriber
  • 2 Interface
SIS Instances
  • 10 (per VirtuoSIS)
  • 1 (per VirtuoSIS)
Max Stations
  • 1,120 (IoIP or SIP)

  • 24 (if all SIP)
Upgrade to Pro

Additional Notes
  • Both still require SIS-DONGLES and/or IoIP Stations for licensing
  • Starter: one slot must be dedicated to IoIP for DONGLES. Therefore, only 3 slots are left for an all SIP solution.
