The biggest advantage of the UNii is undoubtedly the use of one hardware for all applications. The UNii 32, 128, 512, concentrator and redundant PBX all use the same hardware. This is a very big advantage for a number of reasons:
1. Only one type of hardware as spare parts in the bus and warehouse
2. Always the right replacement PCB on hand
3. No hardware replacement in case of system expansion
4. Training only on one hardware
This makes the cost of ownership for an installer significantly lower than other products that use different hardware for each application.
