Edvina.net is a company with many year's experience in TCP/IP networking and IP Communication solutions. During the last five years, we've focused on Unified Communication based on Open Standards - mainly SIP and XMPP/Jabber. We strongly believe that the realtime network for your business is a very longterm investment, like the e-mail system, and needs to be protected by Open Standards, defined by the IETF. In addition, using Open Source Software keeps the costs under control and creates very stable, scalable and profitable solutions. Open Unified Communication in short - using Internet tecnology for business use, making sure that your realtime network - voice, video, chat, presence - will be a network that you can easily expand, build on and continue to use for many years.

The SIPit, or Session Initiation Protocol Interoperability Test, is a weeklong event where people bring their SIP implementations to ensure they work together. Each SIPit is open to anyone with a working SIP implementation. The goal of the events is to refine both the protocol and its implementations. SIPit is a driving force shaping SIP into a globally interoperable protocol for real time Internet communication services. Currently, SIPit is held twice a year.
