endpoint:
VoIP Principles
Physical Features of Endpoint

VoIP
VoIP (Voice over Internet Protocol) is a technology that uses the Internet Protocol instead
of traditional Public Switch Telephone Network (PSTN) technology for voice
communications.
It is a family of technologies, methodologies, communication protocols, and
transmission techniques for the delivery of voice communications and multimedia
sessions over IP networks. The H.323 and Session Initiation Protocol (SIP) are two
popular VoIP protocols that are found in widespread implementation.
H.323
H.323 is a recommendation from the ITU Telecommunication Standardization Sector
(ITU-T) that defines the protocols to provide audio-visual communication sessions on
any packet network. The H.323 standard addresses call signaling and control,
multimedia transport and control, and bandwidth control for point-to-point and
multi-point conferences.
It is widely implemented by voice and video conference equipment manufacturers, is
used within various Internet real-time applications, such as GnuGK and NetMeeting,
and is widely deployed by service providers and enterprises for both voice and video
services over IP networks.

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 endpoints. 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.
Video conferencing endpoints 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 endpoints.
In order to operate endpoints in your network successfully, the endpoints 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.
The latest (or compatible) firmware of endpoint is available.
A call server is active and configured to receive and send SIP/H.323 messages.
