Refurbished Digital Phones for Business Phone Systems
A digital phone is a desk handset that connects to a digital phone system (PBX) over ordinary telephone cabling and uses that maker’s own signalling. It only works with its own make of system, so an Avaya digital phone needs an Avaya system and a Panasonic digital phone needs a Panasonic system.
This range covers new and refurbished digital phones from Avaya, Panasonic, Nortel, Aastra, Siemens, LG, Samsung, NEC, Alcatel, Toshiba, Ericsson and Mitel. It is for offices that keep an existing system running, add extensions or replace a faulty handset. For a phone that works on any standard line, see Analogue Phone.

How to choose a digital phone
Match the system model
Find the make and model of your phone system first, then the phone series it supports. Older and newer series from the same maker do not always mix. If you are unsure, send the system model and a photo of the phone label through a quote request.
Check for a spare port
Each digital phone needs its own digital extension port on a card inside the system. Analogue and IP ports will not run it. If every port is in use, you may need an extra extension card first.
Display and programmable keys
Basic models suit corridors, kitchens and warehouses. Display models show caller ID, extension names and call logs. Models with more programmable keys, such as the Avaya 9408 or Alcatel 4039, suit reception and team leaders who watch other extensions.
Power and add-ons
Most digital phones take power from the system over the phone cable, so they need no mains adaptor. Some series accept a key expansion module or headset adaptor. Check that each add-on matches your phone series.
Moving on from digital
If you plan to move to network phones, see IP Phone for system IP handsets. We also buy used phones and systems, so tell us the make, models and quantities you want to sell.

Questions
What is a digital phone?
A digital phone is a system handset that talks to a digital phone system using the maker's own digital signalling over a telephone cable. It needs a digital extension port on a compatible system. It will not work on a standard phone line or a VoIP service.
Will a digital phone work with any phone system?
No, a digital phone only works with its own make of system, and often only with certain system models. An Avaya 9408 will not run on a Panasonic system, for example. Send us your system model through the quote form and we can check the match.
Are refurbished digital phones a good way to extend an old system?
Yes, for many older systems refurbished digital phones are the main way to add or replace handsets, because the maker no longer produces that range. Choosing the model you already use keeps the same keys and menus for your staff.
Can I mix digital and IP phones on one system?
Often yes, if your system is a hybrid model with both digital ports and IP licences. Avaya IP Office and Panasonic KX-NS are common examples. Check your system's cards and licences before you add IP phones.
Do you sell digital phone systems?
Yes, complete systems, cards and modules are listed under Phone Systems. This page covers the digital phones that connect to them. Match the phone to the system make and model, since digital phone equipment from different makers does not mix.
