BE4000 supports one appliance per site, with up to 200 device registrations (a phone is 1 registration; an ATA acts as 2 devices and so uses 2 device registrations). It is a standalone appliance with no option for clustering and cannot join or be used with an existing Cisco Unified Communications Manager or Cisco Unified Communications Manager Express.
When using the Setup Assistant wizard in the BE4000 Partner Portal, Region Settings selection for Country is used for language selection (phone localization and voicemail). Country is also used for dial plan. Only one language is supported per appliance.
A minimum internet download speed of 2 Mbps is required.
