This
show ephone
output shows two configured ephones: one currently registered (ephone
1) with the IP address 172.30.60.31 and the other currently unregistered (ephone 2).
Tip:
If you ever see a phone's status shown as DECEASED in the show ephone output,
the CME router has lost connectivity with the IP phone through a TCP keepalive failure.
The UNREGISTERED status indicates the CME router closed the connection to the IP
phone in a normal manner.
With the ephone linked to a physical Cisco IP Phone, you can now begin assigning the
buttons to the ephone-dns.
Associating Ephones and Ephone-DNs
Linking ephones and ephone-dns is probably the most confusing section of the CME con-
figuration because there are so many options. You can assign ephone-dns by using the
button command from ephone configuration mode. The basic syntax of this command is
as follows:
button
<physical button> <separator> <ephone-dn>
Example 5-9 demonstrates the basic use of the
button
command.
Example 5-9
Assigning Ephone-DN 2 to Button 1 on Ephone 1
Key
To p i c
CME_Voice(config)#
ephone 1
CME_Voice(config-ephone)#
button 1:2
CME_Voice(config-ephone)#
restart
The button 1:2 syntax assigns ephone-dn 2 (configured in Example 3-5) to button 1 of
ephone 1. The colon (:) separator designates that this is a “normal ring” button assignment.
That is, calls to 1001 (the number of ephone-dn 2) causes the IP phone to audibly ring and
the light on the handset to blink. The restart syntax causes the phone to perform a warm
reboot and redownload its configuration file from the TFTP server. Figure 5-2 illustrates
what the physical IP phone looks like after making this assignment.
You can assign multiple lines to a phone by either entering multiple button commands, as
shown in Example 5-10, or putting multiple entries on the same line, as shown in
Example 5-11.
