What Features are Supported on the Cisco Unified IP Phone
7960G and 7940G?
The Cisco Unified IP Phone 7960G and 7940G function much like digital business phones, 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 covers the following topics:
• Feature Overview, page 1-6
• Configuring Telephony Features, page 1-6

Session Initiation
Protocol (SIP)
SIP is the Internet Engineering task Force
(IETF) standard for multimedia conferencing
over IP. SIP is an ASCII-based,
application-layer control protocol (defined in
RFC 3261) that can be used to establish,
maintain, and terminate calls between two or
more endpoints.
Like other VoIP protocols, SIP is designed to
address the functions of signaling and session
management within a packet telephony network.
Signaling allows call information to be carried
across network boundaries. Session management
provides the ability to control the attributes of an
end-to-end call.
Skinny Client Control
Protocol (SCCP)
SCCP includes a messaging set that allows
communications between call control servers
and endpoint clients such as IP Phones. SCCP
is proprietary to Cisco Systems.
Cisco Unified IP Phones use SCCP for call
control. You can configure the Cisco Unified
IP
Phone to use either SCCP or Session Initiation
Protocol (SIP).
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.
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 the IP address of
the TFTP server using 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.
