VoIP (Voice over Internet Protocol) is a way to make phone calls using the Internet as the transmission method, rather than a landline. With our system, you can make and receive calls from other VoIP users, mobile users, and people with ordinary landlines. The integration between PSTN and VoIP is complete, and undetectable to callers.
How it works Just like a modem converts digital signals form the PC into analogue (voice) traffic for transmission over a phone line, a VoIP-enabled phone or VoIP adaptor converts your voice into digital packets (using the SIP protocol) for transmission over the Internet. If you make a call to another VoIP Phone, the opposite process occurs at the other end, and your voice emerges intact from the ether. If you make a call to a mobile or landline, our gateway decodes the call and sends it on as an ordinary voice call to the PSTN.
The diagram shows in simple form how calls are routed. User A dials the number for user B. The VoIP phone logs onto our routing server, which looks up the destination and sets up the call. Thereafter, the voice traffic passes directly over the Internet between A and B. When A calls C, who has a conventional landline or mobile, the VoIP adaptor logs on as before. The routing server looks up the destination and finds it is a PSTN number. The call is routed via the PSTN gateway into the PSTN network as a normal call. Thereafter, traffic passes directly via the gateway. Why use it? The most immediate reason is to cut your business telephony costs. All calls you make to other VoIP phones are free, and calls to other lines are competitively priced. The second reason is to get a fully-featured PBX system for your business for a very modest rental cost. With every VoIP number, you get ten extensions on your virtual PBX, with all the facilities you would expect: voice menu, extensions for specific people, hunt groups, call forwarding, etc. All this is simply setup from an online control panel, which also gives you access to detailed call statistics and billing information. The third advantage is that you can configure your system to give whatever impression you want to customers. For example, if you have associates or employees in other areas of the UK or even abroad, you can give them all extensions on the same number, or their own numbers with the same area code as your head office. No-one need know whether you have city centre offices or a virtual office! Finally, you can have inbound numbers with different area codes (or even international numbers), so you can appear in several phone books, but have a single office. This allows people to make cheap calls to you and choose a “local” business. What you need There are three main elements to the service:
