Van Access is a distributor of Voice over Internet Protocol (VoIP) equipment. Our single focus is on value and our mission is that through us you will get the best value in VoIP equipment. We achieve this by carrying a portfolio of emerging brands of Voice of Internet Protocol (VoIP) telecommunication equipment. Because they are emerging brands, we are able to offer you equipment at substantially lower prices for comparable quality and functions of a global brand. A substantial number of small and medium businesses are looking for cost saving solutions and turning to VoIP to help. However they are finding that the major brand equipment is actually quite expensive. This is where we come in. Small to medium size businesses can at last take full advantage of alternative brands by coming to Van Access.

We are located in Shenzhen, China, which is a major manufacturing hub in Asia. The majority of all Chinese VoIP manufacturers are located here, which gives us unlimited access to a number of different suppliers. We source from equipment manufacturers all over Asia with technologies comparable to major global brands. In fact, many of these manufacturers produce for the major global brands. These emerging brands may be lacking packaging and at times in design, but they are in comparable in quality and features. However, because these emerging brands lack distribution and marketing, they offer their products and services at substantially below market price for their products. We pass through the low cost to you by keeping our operation lean and simple. In the end, you get high quality products at great value, but without the name brand, the fancy wrappings, or too much pampering. Just stuff that works at amazing prices! If that is something you are looking for, we look forward in doing business with you.

SDP Protocols Are Used To Transmit Media Session Information

In 1998, the Internet Engineering Task Force (IETF) published the specification for a Session Description Protocol or SDP as a format that describes parameters for streaming media. The original IETF Proposed Standard was updated in 2006 as RFC 4566. Although the SDP was created as a feature of Session Announcement Protocol (SAP), it can be used with Real-time Transport Protocol, Real-time Streaming Protocol (RTSP), and Session Initiation Protocol, as well as a standalone protocol. Parameter negotiation, session announcement and session invitation are included in the descriptive sessions from the SDP protocol. Rather than transmit data like other types of protocols, an SDP negotiates between media type endpoints, format and properties involved. A session begins when a connection is established, and the session is terminated only after every endpoint is no longer participating.
