SIP
SIP (Session Initiation Protocol) is the Internet Engineering Task Force’s (IETF’s) standard for
multimedia conferencing over IP. It is an ASCII-based, application-layer control protocol
(defined in RFC 3261) that can be used to establish, maintain, and terminate calls between two
or more system. Like other VoIP protocols, SIP is designed to address the functions of signaling
and session management within a packet telephony network. Signaling allows call information
to be carried across network boundaries. Session management provides the ability to control
the attributes of an end-to-end call.
Physical Features
Video conferencing systems are in the overall network topology, which are designed to
interoperate with other compatible equipment, including application servers, media servers,
Internet-working gateways, and other systems.
In order to operate systems in your network successfully, the systems must meet the following
requirements:
A working IP network is established.
VoIP gateway is configured for SIP or H.323, and H.323 gatekeeper is configured for H.323.
You can also deploy Cloud server for Cloud platform.
The latest (or compatible) firmware of system is available.
A call server is active and configured to receive and send SIP/H.323 messages.
The VC400 and the VC120 have same physical interfaces, camera parameters and video
resolutions.
