Ringer Volume 
Control
The Ringer Volume Control feature enables the system 
administrator to control the minimum ringer-volume 
setting and adjust the minimum volume level for the 
ringer. Individual users cannot make the changes to the 
minimum ringer-volume setting.
When a user presses the minus (–) side of the Volume 
button to reduce the ringer volume in an on-hook state, the 
volume decreases only to the configured minimum 
volume-level setting. When the minimum volume level is 
reached, no status message appears.
After a system restart, the minimum ringer volume resets 
to the minimum ringer-volume setting that is received 
from the configuration file. If the system administrator 
configured a new minimum volume level since the last 
startup and the end user had previously set the minimum 
ringer volume lower, the ringer volume will be set to the 
minimum value from the configuration file, not to the 
user’s setting.
This feature does not apply to handset, speaker, and 
headset volumes during calls.
To configure the parameter in the 
Cisco Unified CM Administration application, 
choose Device > Phone, select the appropriate 
IP phones, and scroll to the Product Specific 
Configuration Layout pane.
Services Allows you to use the Cisco Unified IP Phone Services 
Configuration menu in Cisco Unified Communications 
Manager Administration to define and maintain the list of 
phone services to which users can subscribe.

Manager Administration Guide, Cisco

button
Allows users to access services from a programmable 
button rather than by using the Services menu on a phone.
For more information, see:
 • Cisco Unified Communications Manager 
Administration Guide, Cisco Unified IP 
Phone Configuration.
Session Handoff Allows users to switch calls from a mobile phone to 
Cisco Unified devices that share the same line. 
Handsets on all the devices on the shared line 
flash simultaneously.
After a user answers the call from one of the Cisco Unified 
devices, the other Cisco Unified devices that share the 
same line display a Remote in Use message. However, if 
the call fails to switch from the mobile phone, the 
mobile phone maydisplay a Cannot Move 
Conversation message.

Communications Manager Features and 
Services Guide, Cisco Unified Mobility and
