1.5 System Capacities
The maximum number of simultaneous calls is limited by the number of VCM channels of the IP Office and the channels
of the IP Base Stations. The maximum number of simultaneous calls can also be affected by the direct media
configuration in the IP Office Manager.
Base Stations
The IP DECT base stations have the following capacity.
· Up to a maximum of 32 base stations are supported.
· 1 base station must be set as the ADMM. This does not affect the base stations call handling. However this base
station must remain in the system at all time for the IP DECT system to be operational.
· Each base station can support up to 8 simultaneous calls to/from DECT phones.
· Additional calls are only possible if another base station with free capacity and with appropriate signal strength is
within range.
IP DECT Phones
The IP DECT system supports the following phone capacity when used with IP Office:
· Up to 120 IP DECT phones are supported.
· Up to 100 IP DECT phones can be active simultaneously.
· It is recommended that no more than 50 handsets are active simultaneously if the ADMM base station is also being
used for DECT wireless call connection. If necessary the DECT functions of the ADMM base station can be disabled.
· As detailed above, a maximum of 8 DECT phones can be connected via any single base station at any time.
· The IP DECT system supports GAP compatible DECT handsets. However only basic functions to make and answer
calls are supported on these devices.
