Network Requirements
For the Cisco Unified SIP Phone 3911 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 Communications Manager 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
Communications Manager. If the Cisco Unified Communications Manager server
is located in a different time zone than the phones, the phones will not display the
correct local time.

handle call processing. Refer to

Communications Manager application to ensure that Cisco Unified
Communications Manager is set up properly to manage the phone and to properly
route and process calls.

configured in Cisco Unified Communications Manager before connecting any
Cisco Unified IP Phone to the network. See the
