Your voicemail system is separate from the phone. If you need information about the voicemail system phone
numbers for internal and external access and other voicemail system information, contact your administrator.

Self Care Portal
You can customize some phone settings with the Self Care portal web site, which you access from your
computer. The Self Care portal is part of your organization's Cisco Unified Communications Manager.
Your administrator gives you the URL to access the Self Care portal, and provides your user ID and password.
In the Self Care portal, you can control features, line settings, and phone services for your phone.
•
Phone features include speed dial, do not disturb, and your personal address book.
•
Line settings affect a specific phone line (directory number) on your phone. Line settings can include
call forwarding, visual and audio message indicators, ring patterns, and other line-specific settings.
•
Phone services can include special phone features, network data, and web-based information (such as
stock quotes and movie listings). Use the Self Care Portal to subscribe to a phone service before you
access it on your phone.
The following table describes some specific features that you configure with the Self Care portal. For more
information, see the Self Care portal documentation for your call control system.
DescriptionFeatures
Use the number that will receive calls when call forward is enabled on the phone. Use
the Self Care portal to set up more complicated call forward functions, for example,
when your line is busy.
