• User Guide

This is an IP phone and can have firmware loaded to make it operate directly with an IP provider. The firmware upgrade process can be complex and we recommend it is not done unless you have previous experience. If you are looking for an IP phone that will work directly with an IP provider then we recommend Yealink, Polycom and Grandstream telephones.

This phone can be powered over Ethernet (PoE), thus POWER SUPPLY IS NOT INCLUDED unless stated.
