Overview
The SIP solution provides extensive telephone features including superior voice quality, customer cost-
savings, support for real-time communications, and improved efficiency of communications.
SIP-enabled phones, in conjunction with the UC server, offer a wide range of phone features, such as call
park/pickup, overhead paging, auto attendant, single button voicemail access, caller ID, conferencing, hunt
groups, ring groups, message waiting indicator, music on hold, and more.
The UC server works with many types of SIP-compliant phones. However, phones from different
manufacturers are configured differently, and the phone features are accessed in a different way.
Customizing your Phone
In the UC server you can customize your phone to suit your personal preferences. For example, you can set
the number of rings before your phone goes to voicemail. You can also set how the message waiting light
on your phone operates. For example, whether the message waiting light on your phone turns off when
you've accessed your first new voicemail message, or when you've accessed all your new voicemail
messages. You can also customize your phone according to your particular phone's make and model. For
information on customizing your phone in the UC server, refer to the following sections.
• Changing the number of rings before calls go to voicemail on page 56
• Setting the message waiting light on your phone on page 56
