How to work from home with your 3CX Phone System

With a 3CX phone system already in place, your business is already in a strong position to cope with the sudden demand for home working.  It is a fairly easy process to be able to take calls from home and work as if you were sat at your extension in the office.


We are seeing a huge demand for homeworking set-ups at the moment. Here are some frequently asked questions about homeworking with your 3CX

How do I install 3CX on my smartphone?
  • If you haven’t already set up the 3CX app on your smartphone, simply download the iOS or Android 3CX app from Google Play or App Store.
  • Open the 3CX Welcome email you would have received when your 3CX phone system was initially installed (if you no longer have this, please contact our support team, and they will re-issue it to you*)
  • Open the app on your phone, tap on the menu (top left), then click on “Scan QR Code”
  • Now scan the QR Code from your welcome email
  • That’s it, you’re all done!
How do I install 3CX on my desktop?
  • Open the 3CX Welcome email you would have received when your 3CX phone system was initially installed (if you no longer have this, please contact our support team, and they will re-issue it to you*)
  • Go to your webclient URL specified in your welcome email
  • Login using your extension and password
  • That’s it, you’re all done! You can use your handsfree mobile headphones to make/receive calls, but if you would like a more comfortable headset that’s compatible with your laptop, please contact us and we’ll give you some ideas.
What if I don’t like using the apps and would prefer to use a handset? Can I just take my deskphone home?


  • Whilst it is possible to reconfigure the IP phones for home users this isn’t straightforward and there are a number of things to consider:
  1. PSU – Most home routers don’t support POE so end users will need a power supply for the IP phone
  2. The phones may be configured with a VLAN so they will not automatically pickup an IP when connected to a home router.
  3. Generally the home router isn’t in the same location as where the phone needs to operate so cabling can be an issue
  • If you still wish to take your deskphone at home, please contact our support team before you do this, as we will need to take a back up of your phone in order for it to re-provision correctly at home. The 3CX phone system is backed up, but the handset configuration is stored in the phone.  We need the handset connected to the corporate network on the correct VLAN to be able to save the configuration.
  • If the phones have been removed from the network already they would need to be defaulted and reprogrammed to work on the home users broadband. This is going to be time consuming as essentially we would need to re-install all of your phones as if it were a new installation, so we would have to charge for our time to reconfigure the devices and then revert the changes when the phones are moved back to the office.
  • Send in a support request to our team, and they can help identify if there is a more suitable solution for you.
If I can’t take my deskphone home, is there an alternative handset I can use?
  • We recommend supplying a wireless IP handset.  This can be pre-configured with your extension details already set up, as per your deskphone.  We will then ship this out to either a centralised office, or direct to home addresses.
  • Please contact us with the number of handsets required, so we can provide costings for this. We can provide discounts on bulk purchases.

Take a look at the 3CX Quick Start Guide for more information on how to use the apps, including how to make/receive/transfer calls, access voicemail, set up web and audio conferencing and using chat.  And of course, if you need any help, just give us a shout!

*Remote charges will be applicable for set up assistance

**Whilst we endeavour to provide handsets swiftly, please be aware that there is a national shortage of power supplies and USB headsets.  There may be a potential delay in stock supply as the Coronavirus situation progresses.  We advise that you contact us with your requests as early as possible.
