How many devices you need depends on. 

  • DECT Measurement
  • Call Capacity
  • Number of handsets
  • Codec used


SystemIntegrator + Manager + BaseIntegrator + ManagerBaseMaximum number of handsetsMaximum number of Parallel calls
Small1
2 - 95020
Medium
11 - 6025060

If you need more then:

  • 50 Handsets
  • 20 Parallel calls
  • 10 Base stations

You switch from Small to Medium size system and the Integrator + Manager is not an DECT base anymore, so you need one extra device. There is no license needed.
