3CX supports a large number of phones, divided into supported phones and legacy phones – What’s the difference and what’s changing?
Supported phones are from companies with whom 3CX has an active partnership which allows us to fully support the phones – it means all 3CX features are implemented on these phones, new firmware is tested and provided for download to 3CX customers and new models are supported, provided they are compatible with 3CX.
Legacy phones are phones from vendors with whom 3CX does not have an active partnership, but these phones can be supported to allow for easy migration from older phone systems. In some cases these phones are also no longer available on the market or no new firmware is being supplied for these phones. These phones might also have several limitations compared to newer supported phones. Whilst we support the use of legacy phones connecting to 3CX within their limitations, we never suggest to buy these phones on the market – be it new or via amazon.
