Videoconferencing endpoints typically are compatible with SIP or H.323,
and in some cases (like Avaya Scopia
®
XT Series), an endpoint can be
compatible with both protocols. As a protocol, it uses fewer resources than
H.323.

SIP Server A SIP server is a network device communicating via the SIP protocol.
SIP URI See URI on page 97.
Slider See Content Slider on page 85.
SNMP Simple Network Management Protocol (SNMP) is a protocol used to
monitor network devices by sending messages and alerts to their registered
SNMP server.
Software endpoint 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, Scopia
Desktop Client or Scopia Mobile.
SQCIF
SQCIF defines a video resolution of 128 x 96 pixels.
SRTP 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.
SSO

Standard Definition See SD on page 94.
Streaming Streaming is a method to send live or recorded videoconferences in one
direction to viewers. Recipients can only view the content; they cannot
participate with a microphone or camera to communicate back to the
meeting. There are two types of streaming supported in Equinox Solution:
unicast which sends a separate stream to each viewer, and multicast which
sends one stream to a range of viewers.
STUN
A STUN server enables you to directly dial an endpoint behind a NAT or
firewall by giving that computer’s public internet address.
SVC SVC extends the H.264 codec standard to dramatically increase error
resiliency and video quality without the need for higher bandwidth. It is
especially effective over networks with high packet loss (like wireless
