On 17 August 2020, the Conference Phone 2220 was discontinued and is no longer available to purchase. Phone 2220s that are currently in use by organizations will still be supported.

View the installation instructions on the installation sheet that accompanies the StarLeaf Conference Phone 2220 (Conference Phone) and the information on this page, before you connect the Conference Phone to its power source.


Do not block any of the ventilation openings of the Conference Phone.

Avoid installing the Conference Phone near a heat source such as a radiator and avoid placing it in direct sunlight.


Do not remove the cover of the Conference Phone. There are no user-serviceable parts. If you open the Conference Phone or remove its cover you may expose yourself to dangerous voltages or other hazards, and you will invalidate the warranty.

Power requirements

The Conference Phone is powered using Power-over-Ethernet (PoE) supplied by a Power Sourcing Equipment (PSE) unit. The Conference Phone must be connected to a PSE unit approved by StarLeaf, such as the StarLeaf PoE++ Midspan Injector, part number 712-00050.

The plug that connects AC power to the PSE unit is the main disconnect device for the Conference Phone and must always be easily accessible.

Ensure that the AC supply to the PSE unit incorporates over current protection rated by a maximum of 10A (15A for North America).

Caution: Over-current devices must meet applicable national and local electrical safety codes and be approved for the intended application.

To avoid overheating, do not obstruct airflow to the PSE unit. Avoid installation of the PSE unit near a heat source such a radiator and avoid placing it in direct sunlight.

Do not remove the cover of the PSE unit. There are no user-serviceable parts. If you open the PSE unit or remove its cover you may expose yourself to dangerous voltages or other hazards and you will invalidate the warranty.

The Conference Phone and PSE unit use RJ45 data sockets. These data sockets are qualified as Safety Extra-Low Voltage (SELV) circuits and must only be connected to SELV interfaces on other equipment using intra-building cabling. Do NOT connect these circuits to the telephone network nor to cabling that exits the building.

The table below shows the power ratings of the Conference Phone when it is powered by the PoE++ Midspan Injector:
