Security by Design

To ensure that every business call is kept private, Maxwell 4 benefits from end-to-end encryption using industry standard Secure Real-Time Transport Protocol (SRTP) or the more advanced Transport Layer Security (TLS) standard. Each unit is further secured with touch gesture unlock code to prevent unauthorised usage.


Flexible and Adjustable

The 4.3 inch capacitive colour touchscreen with adjustable contrast controls plus an additional 38 programmable soft keys makes the Maxwell 4 an ideal IP phone for any small office or big business environment. Ease of use is further enhanced through a flexible stand design offering multiple viewing angles and mounting options to deliver an optimum business communication experience.
