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 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.

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.
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.
SRTP
Secure Real-time Transport Protocol (SRTP) adds security to the standard RTP protocol, which is used
to send video and audio data between devices in SIP calls using TLS. It offers security via encrypting,
authenticating and ensuring message integrity.
