Presence is displayed in any standards-based IP phone, as well as in 3CX Assistant and the MyPhone user portal.

3CX is the only IP PBX to include a free Windows VoIP phone that can be used in or out of the office. 3CX soft phone and the traditional hardware phone can be used at the same time using the same credentials. For example, the hardware phone can be used when at the office, but when at home or on the road it is very easy to switch to the soft phone and remain connected to the company’s phone system.

With 3CX, network managers break free from the archaic user interfaces of conventional PBXs and from the traditional PBX vendor. With the intuitive web-based console, administrators can easily create extensions and make PBX configuration changes, without needing the PBX vendor.
