SIF defines a video resolution of 352 x 240 pixels (NTSC) or 352 x 288
(PAL). This is often used in security cameras.
Signaling, also known as call control, sets up, manages and ends a
connection or call. These messages include the authorization to make the
call, checking bandwidth, resolving endpoint addresses, and routing the call
through different servers. Signaling is transmitted via the H.225.0/Q.931
and H.225.0/RAS protocols in H.323 calls, or by the SIP headers in SIP
calls. Signaling occurs before the control aspect of call setup.
Single Sign On (SSO) automatically uses your network login and password
to access different enterprise systems. Using SSO, you do not need to
separately login to each system or service in your organization.
Session Initiation Protocol (SIP) is a signaling protocol for starting,
managing and ending voice and video sessions over TCP, TLS or UDP.
Videoconferencing endpoints typically are compatible with SIP or H.323,
and in some cases (like Avaya Scopia
compatible with both protocols. As a protocol, it uses fewer resources than
H.323.
See Registrar on page 86.
A SIP server is a network device communicating via the SIP protocol.
See URI on page 90.
See Content Slider on page 78.
Simple Network Management Protocol (SNMP) is a protocol used to
monitor network devices by sending messages and alerts to their registered
SNMP server.
A software endpoint turns a computer or portable device into a
videoconferencing endpoint via a software application only. It uses the
system's camera and microphone to send image and sound to the other
participants, and displays their images on the screen. For example,

SQCIF defines a video resolution of 128 x 96 pixels.
Secure Real-time Transport Protocol (SRTP) adds security to the standard
RTP protocol, which is used to send media (video and audio) between
devices in SIP calls. It offers security with encryption, authentication and
message integrity. The encryption uses a symmetric key generated at the
start of the call, and being symmetric, the same key locks and unlocks the
data. So to secure transmission of the symmetric key, it is sent safely
during call setup using TLS.
