In this text you can find the terms connected to SIP servers and how to make a use of having an account in them. If you would like to build up/modernise your communication system, having a basic knowledge on SIP servers is a must.

As Figure 1 represents, the SIP clients (a VoIP Phone and a softphone on a computer) connect to the SIP server, the Ozeki Phone System PBX with a SIP connection. The SIP server is also connected with a SIP connection to the Internet: via the Internet, the SIP server can connect to all types of telecommunication systems (to another VoIP Phone and another server in this Figure) - what will make it possible to call anyone in the world who has a phone number or an IP address.

SIP and SIP Server

The Session Initiation Protocol (SIP) is designed to create communication channels between two or more participants through the Internet. SIP can manage real-time multimedia sessions, so real-time dials that are not necessarily phone calls but chat, audio and/or video calls and even instant messaging, audio and/or video conferences can be organised. SIP is the signaling protocol of VoIP, Voice over Internet Protocol.

The SIP server is the centre of an Internet-based communication system: the caller connects to the server (that is also known as PBX Private Branch eXchange or PABX, Private Automated Branch eXchange), and the server will forward the call to the proper destination. This whole process is done through the Internet what leads to maximum reliability and high quality.

How to Use a SIP Server?

In order to use a SIP server, you have nothing else to do but to create a SIP account: this can be done with a simple registration to the Ozeki Phone System. The process is as easy as creating an e-mail account: just give the user data and your SIP account is created.

If you need a SIP account, you may download the Ozeki Phone System software on your computer or phoning device, and after the installation and some configuration, your computer or device becomes a SIP client and your communication system is ready for using.
