Are there 3CX compatible analogue phones?

It is possible to use an analogue phone device with a VoIP telephone system, such as 3CX. You can use an ATA adapter. An ATA adapter allows you to connect into an ethernet network jack into the adapter and then connect the phone into the adapter. Your old phone will appear to the 3CX VoIP phone system software as a regular SIP phone.

The best advice is to check with Gulaga Networks first to make sure your phone is 3CX compatible and supported. Make sure they are newer generation and likely to be provided with software updates for an extended period of time, to ensure testing and compatibility with 3CX. Gulaga Networks can guide you on the most compatible 3CX phone to align with your business goals.
