The Master Unit controls one or more Slave Units (15 Max).
NB: System redundancy is not supported, if the Master unit fails, calls will not be possible via the Slave units (TBC)
If ‘Slave’ units are installed in Branch Offices, local calls can be made using local trunks.
The Slave units can also support additional extensions and UM features.
