What Features are Supported on the Cisco Unified IP Phone
7965G and 7945G?
The Cisco Unified IP Phone functions much like a digital business phone, allowing you to place and
receive telephone calls. In addition to traditional telephony features, the Cisco Unified IP Phone includes
features that enable you to administer and monitor the phone as a network device.
This section includes the following topics:
• Feature Overview, page 1-7
• Configuring Telephony Features, page 1-8

Feature Overview
Cisco Unified IP Phones provide traditional telephony functionality, such as call forwarding and
transferring, redialing, speed dialing, conference calling, and voice messaging system access.
Cisco
Unified IP phones also provide a variety of other features. For an overview of the telephony
features that the Cisco
Unified IP Phone supports, see the “Telephony Features Available for the Phone”
section on page 5-2.
Transmission Control
Protocol (TCP)
TCP is a connection-oriented
transport protocol.
Cisco Unified IP Phones use TCP to connect to Cisco
Unified
Communications Manager and to access XML
services.
Transport Layer
Security (TLS)
TLS is a standard protocol for
securing and authenticating
communications.
When security is implemented, Cisco Unified IP Phones
use the TLS protocol when securely registering with Cisco
Unified
Communications Manager.
Trivial File Transfer
Protocol (TFTP)
TFTP allows you to transfer files
over the network.
On the Cisco Unified IP Phone,
TFTP enables you to obtain a
configuration file specific to the
phone type.
TFTP requires a TFTP server in your network, which can be
automatically identified from the DHCP server. If you want
a phone to use a TFTP server other than the one specified
by the DHCP server, you must manually assign TFTP server
from the Network Configuration menu on the phone.
User Datagram Protocol
(UDP)
UDP is a connectionless messaging
protocol for delivery of data packets.
Cisco Unified IP Phones transmit and receive RTP streams,
which utilize UDP.
