over IP (VoIP) calls, SIP can also be used for video or any media type.

SIP is a text-based protocol that is based on HTTP and MIME, which makes it suitable and very flexible for

integrated voice-data applications. SIP is designed for realtime transmission, uses fewer resources and is

considerably less complex than H.323. Its addressing scheme uses URLs and is human readable; for

SIP relies on the session description protocol (SDP) for session description and the realtime transport

protocol (RTP) for actual transport.

SIP Proxy

The softswitch from/to which all SIP signaling is sent and received. In other words, the VOIP2320 VOIP platform.

Traffic Shaper

Component of VOS providing prioritization of voice and signaling traffic over other “data” traffic. It also

provides outbound bandwidth shaping so that no queuing occurs upstream of the EdgeMarc as well as

throttling of inbound TCP data traffic to avoid swamping of inbound voice.

VOS

Voice Operating System for the EdgeMarc router(s). Includes all the software functionality provided by

Edgewater; both Edgewater developed software as well as the Linux O/S and other open-source packages.

WAN

Wide Area Network. A computer network covering a broad geographical area. WANs are used to connect

local area networks (LANs) together, so that users and computers in one location can communicate with

users and computers in other locations. The largest and most well-known example of a WAN is the Internet.
