CME: Ephones and Ephone-DNs, Part 1

Describing + configuring Ephones and Ephone-DN

Ephone-DNs represent Directory Numbers

2 Flavours:

  • If on active call, incoming call receives a busy signal

Dual Line

  • Necessary for call waiting, conference calling and consultative transfers

Understanding Ephones

  • Are linked to the device by MAC address
  • Printed on the box of Cisco IP Phone
  • Printed on the back of the Cisco IP Phone
  • From the Settings > Network cfg on the IP Phone
  • Show in CDP
