Configuring a DECT Phone

Introduction

3CX also supports the use of DECT Phones. DECT phones are wireless phones which have a number of advantages over Wi-Fi phones:

  • DECT is very reliable and independent of your Wi-Fi  
  • No need for staff to use personal phones
  • Cheap, long lasting, easily replaced hardware
  • Long battery life
  • Scale up according to business needs

DECT IP Phones can support a number of base stations and between 5 to 100 handsets depending on vendor and model. You would need multiple base stations in case you have a big office.

Configure your DECT Base

To configure a DECT Phone, you need to first configure a base station and then assign the handsets to each user.

  • Click on Admin > Voice & Chat > +Add DECT/FXS

  • Select your model and enter the base station’s MAC address.

  • If your instance is in the cloud, select a router phone or SBC behind which it will work.

  • Assign the users and click on Add DECT Base Station. You will be able to assign more users after the set-up.

  • Click the Close button, and reboot the base station.
