WHY IS THERE ONLY ONE CABLE TO MY PHONE
Although the phones are designed to have a local AC power supply attached, we have provisioned the phones to run off of PoE.
PoE, which stands for Power over Ethernet, draws power from the network.
By using PoE for the phones, they can be placed anywhere an Ethernet connection is, and not where a power outlet is.
This allows for flexibility of placement of phones for the network administrators.
