What you will need
A SIP account or an IP-PBX / hosted VoIP service that supports SIP phones, and an Ethernet connection. For PoE you need an IEEE 802.3af switch or injector; otherwise a DC 5V/600mA Yealink adapter, which Yealink lists as optional in the box. Call us to check compatibility with your phone system.
