protocols today, including H.323, SIP and the streaming control protocol
known as RTSP. The secured version of RTP is SRTP.
RTSP RTSP or Real-Time Streaming Protocol controls the delivery of streamed
live or playback video over IP, with functions like pause, fast forward and
reverse. While the media itself is sent via RTP, these control functions are
managed by RTSP
Sampling Rate
The sampling rate is a measure of the accuracy of the audio when it is
digitized. To convert analog audio to digital, it must collect or sample the
audio at specific intervals. As the rate of sampling increases, it raises audio
quality.
SBC
A Session Border Controller (SBC) is a relay device between two different
networks. It can be used in firewall/NAT traversal, protocol translations and
load balancing.
Scalability Scalability describes the ability to increase the capacity of a network device
by adding another identical device (one or more) to your existing
deployment. In contrast, a non-scalable solution would require replacing
existing components to increase capacity.

SD 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.
Service Also known as MCU service. See Meeting Type on page 208.
SIF SIF defines a video resolution of 352 x 240 pixels (NTSC) or 352 x 288
(PAL). This is often used in security cameras.
Signaling 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
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.
SIP 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
