Network Requirements
For the Cisco Unified SIP Phone 3951 to successfully operate as a Cisco Unified
IP Phone endpoint in your network, your network must meet the following
requirements:
•
Working Voice over IP (VoIP) Network:
–
VoIP configured on your Cisco routers and gateways
–
Cisco Unified CallManager installed in your network and configured to
handle call processing
•
IP network that supports DHCP or manual assignment of IP address, gateway,
and subnet mask
The Cisco Unified IP Phone displays the date and time from Cisco Unified
CallManager. If the Cisco Unified CallManager server is located in a different
time zone than the phones, the phones will not display the correct local time.
Cisco Unified CallManager Configuration
The Cisco Unified IP Phone requires Cisco Unified CallManager to handle call
processing. Refer to
Cisco Unified CallManager Administration Guide
or
context-sensitive help in the Cisco Unified CallManager application to ensure
that Cisco Unified CallManager is set up properly to manage the phone and to
properly route and process calls.
If you plan to use auto-registration, verify that it is enabled and properly
configured in Cisco Unified CallManager before connecting any
Cisco Unified IP Phone to the network. See the
“Adding Phones to the Cisco
Unified CallManager Database” section on page 2-9
for details.
You must use Cisco Unified CallManager to configure and assign telephony
features to the Cisco Unified IP Phones. See the
“Telephony Features Available
for the Cisco Unified IP Phone” section on page 5-1
for details.
In Cisco Unified CallManager, you can add users to the database and associate
them with specific phones. See the
“Adding Users to Cisco Unified CallManager”
section on page 5-4
for details.
