VoIP and SIP are both acronyms that stand for
Voice over Internet Protocol and Session Initiated Protocol.

VoIP is a term for using the Internet as a means of transmitting your voice for telephone calls instead of using the normal telephone service through companies like British Telecom.

People are switching to VoIP for the substantial savings on their phone bills that VoIP can provide. To use VoIP, you will need a broadband connection: either DSL or cable.

You will also need some type of SIP device (a SIP router, ATA or a SIP phone). You may also use your computer for calls if you have a headset with a microphone.

There is no affiliation with any telephone company, so it will not affect your BT or telecom provider. You will not have to give up your phone line or even tell your phone company that you have a VoIP line.

Session Inintiated Protocol is the technical name that puts the sip in sipgate! It is an efficient system for routing calls through the Internet much like web pages are routed to your browser when you surf the Internet.
