Guide - replace a phone

If you need to replace a phone as one has died, or you are simply upgrading then this guide should provide you with everything you need to know about how to go about it. If you do need any further help with this process then please contact us.

This guide will be Polycom centric, but you can apply most of it to other phones.

Initially, you need to identify if you have VLANS. There are 2 easy ways to check for this. If VLANS are present, your existing phones will be plugged straight into your computer and the phones that you are using will be Polycom 102's. If you have VLANS then please follow the instructions Replacing a Phone with VLANS.

Replacing your phone

Firstly, you have to enable ZTP in the babblevoice console for your new phone:

  1. Go to and login.
  2. Click on Devices.
  3. Select the device (or phone!) that you are replacing.
  4. Click Edit.
  5. Click the ZTP tab.
  6. The serial number (MAC address) of the old phone then needs to be removed by clicking the x button.
  7. Now you can enter the serial number of the new phone - this is found on the bottom/back of the base unit of your new phone.
  8. Click Save and Close.

You can now replace the phone - attach the cable into the wall port, plug it in and power it up!
