Standard Definition (SD), is a term used to refer to video resolutions which
are lower than HD. There is no consensus defining one video resolution for
SD.
Also known as MCU service. See
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.

A SIP server is a network device communicating via the SIP protocol.

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,
