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 some users before you click on “Add DECT Base Station” (Without at least one user assigned, the DECT Base Station will not register with the PBX). You will be able to assign more users after the set-up.

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