VoIP (pronounced voyp) is the name for a voice telephone call transmited over a computer network , usually a broadband connection. VoIP is fast becoming the standard for business communications. It enables a broader array of features and benefits that are impossible using existing telephony.

A Hosted (VoIP) PBX is a complete software based telephone system that is located in a secure remote telecommunications carrier data centre. With a traditional PBX the equipment is sited in the office it is being used in. Just like hosting a web site you can now host your telephone system off site. This means that your company does not need to buy , install or maintain any telephone system equipment on site.

Telephone call control and calling features can be easily managed through a web portal. Calls are made from business grade IP telephone handset and calls are delivered and received over your broadband connection.

Clickphones Hosted VoiP PBX uses SIP (don’t you just love jargin) SIP is an acronym for Session Initiation Protocol (pronounced sip, as in what you do with nice hot cup of tea) is a signaling protocol (set of rules) which is used to set up “real time” communication sessions. It is an “open standard” (freely available without needing you to pay a license fee) and was developed by a lot of clever people working under the umbrella of the Internet Engineering Task Force (IETF)

Real time communication session can involve voice, video, instant messaging, Data Exchange, File Sharing etc. or any mix of the sessions, also it can run on pretty much any device people use for communicating: laptop computer, PDA, cell phone, IM client, IP phone, and so on.
That sounds sexy but the “goodness” is what can it do for me….!

In a nutshell when you “register” with a SIP server you tell it:
1 Who you are
2 Where you are, and
3 What capabilities you have.


This is technical blurb about the device you are using (PC PDA etc) and what software programs you have available .

The upshot of this is that you can be “found” by people who want to communicate with you, you can “find” people who you want to communicate with and the system knows how to set up the communication session in a way that both your devices understand.

But that’s not all SIP servers can be linked to all sorts of other pieces of equipment (gateways etc.) just to broaden the reach of your communication opportunities.Together withour partners we use our SIP server to connect our customers to the Public Switched Telephone Network (PSTN) and allow calls originating from PSTN to be received by our customers. Things can get complicated very quickly in the SIP world simply because of the sheer number of variables involved but we endeavor to take all this pain away from our customers and try to keep things simple.
