Power over
Ethernet (PoE) Switches for 3CX
Recommended IP Phones
3CX is compatible with a wide
variety of SIP based IP phones, most of them are 802.3af Power over Ethernet
compatible. Power
over Ethernet (PoE) is a technology that sends both power and data through an
Ethernet cable. Almost all 3CX recommended IP phones support 802.3af PoE. Using PoE eliminates the need for an external power supply to
power your IP phones. PoE technology reduces installation time, cable clutter
and provides centralized power distribution. If a PoE switch is used in
conjunction with a battery back up system the phones will remain powered on in
the event of an electrical outage.
Please check your specific phone models documentation to ensure compatibility
with 802.3af Power over Ethernet.*
