This command in voice user-profile configuration mode to creates a
line button definition in a user profile to be downloaded to the IP phone when
the user is logged into an IP phone that is enabled for extension mobility.
This command in voice logout-profile configuration mode creates a
line button definition in a default profile to be downloaded to an IP phone
when no user is logged into an IP phone that is enabled for extension mobility.
For button appearance, extension mobility will associate line
definitions in the voice-logout profile or voice-user profile to phone buttons
in a sequential manner. If the profile contains more directory and speed-dial
numbers than there are buttons on the physical phone to which the profile is
downloaded, the remaining numbers in the profile are ignored.
On Cisco Unified IP phones, line definitions are assigned to
available extension buttons before speed-dial definitions, in sequential order,
starting with the lowest directory number first.
After creating or modifying a profile, use the
reset (voice logout-profile or voice
user-profile) command to reset all phones associated with the profile being
configured to propagate the changes.

ring for normal external calls.
A line button that is configured for monitor mode on one phone
provides visual line status for a line that also appears on another phone. When
monitor mode is set for a button with a shared line, the line status indicates
that the shared line is either idle or in use. The line and line button are
available in monitor mode for visual status only. Calls cannot be made or
received using a line button that has been set in monitor mode. Incoming calls
on a line button that is in monitor mode do not ring and do not display caller
ID or call-waiting caller ID. Monitor mode is intended to be used only in the
context of shared lines so that one user, such as a receptionist, can visually
monitor the in-use status of several users’ phone extensions (for example, as a
The line button for a monitored line can be used as a
direct-station-select for a call transfer when the monitored line is in an idle
state. In this case, the phone user who transfers a call from a normal line can
press the Transfer button and then press the line button of the monitored line,
causing the call to be transferred to the phone number of the monitored line.
You can configure silent ring on any type of phone. However, you
typically set silent ring only on buttons of a phone with multiple lines, such
as a Cisco Unified IP Phone 7940 or Cisco Unified IP Phone 7960 and 7960G. The
only visible cue is a flashing icon in the phone display.
If you configure a button to have a silent ring, you will not hear a
call-waiting beep or call-waiting ring regardless of whether the ephone-dn
associated with the button is configured to generate a call-waiting beep or
In Cisco IOS Release 12.4(4)XC and later releases, the silent
ringing behavior is overridden during active night-service periods. Silent
ringing does not apply during designated night-service periods when the
s keyword is used.
Overlay lines are directory numbers that share a single line button
on a multibutton phone. When more than one incoming call arrives on lines that
are set on a single button, the line (ephone-dn) that is the left most in the
number command list is the primary line and
is given the highest priority. If this call is answered by another phone or if
the caller hangs up, the phone selects the next line in its overlay set to
present as the ringing call. The caller ID display updates to show the caller
ID for the currently presented call.
Directory numbers that are part of an overlay set can be single-line
directory numbers or dual-line directory numbers, but the set must contain
either all single-line or all dual-line directory numbers, and not a mixture of
The primary directory number on each phone in a shared-line overlay
set should be a unique ephone-dn. The unique ephone-dn guarantees that the
phone will have a line available for outgoing calls, and ensures that the phone
user can obtain dial-tone even when there are no idle lines available in the
rest of the shared-line overlay set. Use a unique directory number in this
manner to provide for a unique calling party identity on outbound calls made by
the phone so that the called user can see which specific phone is calling.
The name of the first directory number in the overlay set is not
displayed because it is the default directory number for calls to the phone,
and the name or number is permanently displayed next to the phone’s button. For
example, if there are ten numbers in an overlay set, only the last nine numbers
are displayed when calls are made to them.
The same configuration is used for overlaid lines both with and
without call waiting.
Directory numbers can accept call interruptions, such as call
waiting, by default. For call waiting to work, the default must be active. To
ensure that this is the case, remove the
accept command from the configurations of
directory numbers for which you want to use call waiting.
Directory numbers that are part of a cw-overlay set can be
single-line directory numbers or dual-line directory numbers, but the set must
contain either all single-line or all dual-line directory numbers, and not a
mixture of the two.
The Cisco Unified IP Phone 7931G cannot support overlays that contain
directory numbers that are configured for dual-line mode.
