Basic IP Phone Configuration on Cisco Call Manager Express

Written By Harris Andrea

Before showing you how to configure a basic IP phone on Cisco CallManager Express (CCME), you need first to understand the concepts of ephone and ephone-dn.

In CCME, “ephone” (short for Ethernet Phone) refers to the physical IP phone device, and is configured with the Ethernet MAC address of the IP phone. The MAC address of the IP phone uniquely identifies the device on the network and is found on a sticker on the underside of the IP phone or from the phone’s shipping carton label.

The ephone directory number (ephone-dn) refers to the phone lines that are associated with the ephone device. The ephone-dn parameter basically configures the telephone device number. Also, the ephone-dn can use the “dual-line” option which will allow the IP phone to handle two simultaneous calls. The dual-line option also provides a way for the phone to support call waiting, conferencing, call transfer with consultation etc.

Configuration:

In the following configuration we will configure a Cisco 7960 IP phone with two directory numbers 2100 and 2200 on the first two line buttons of the telephone.

    As far as I know you don’t need to configure multicast for Music on Hold. The music stream is transfered as unicast from the CallManager system to the phone.

    You can see the following cisco link for more information about configuring Music on Hold: CME-MOH

    You will need to configure the command multicast-moh under the ephone:
    ephone 1
    multicast-moh
