The Mitel 5330e (50006476) is an executive phone that differs from the regular 5330 version because of dual integrated Gigabit Ethernet ports. The 10/100/1000 Mbps PC and LAN ports mean your phone and computer can share the same network drop without sacrificing network speed. The Mitel 5330e features 24 programmable buttons that are integrated into the large backlit display. The programmable buttons utilize self-labeling technology so you don’t have to waste time printing labels from your computer, just to find out they don’t fit. The 5330e (50006476) IP Phone has 12 fixed feature keys and supports both SIP and MiNET protocols. This Mitel business phone can be powered via PoE (Power over Ethernet) by any 802.3af compliant switch.
