VoIP / SIP Trunks

Bluebox Integration can supply and support various VoIP/SIP line solutions to work in parallel with a range of IP telephone systems.

What is VoIP?
VoIP (Voice over Internet Protocol) is a way to make phone calls using the internet instead of a landline. You can make calls to and receive calls from other VoIP users, mobile phones and ordinary landlines. The integration between conventional telephone or ISDN lines is undetectable to callers.

How does it work?
Just like a modem, converting a digital signal into analogue for transmission over a phone line. A VoIP phone converts sound into digital packets (using SIP protocol) making it suitable for transmission over the internet. If you make a call to another VoIP phone, the opposite process happens at the other end. If you make a call to a mobile or landline, your VoIP providers gateway decodes the call and sends it on as an ordinary voice call to the telephone exchange.

Calling another VoIP line
User A dials the number for user B. The VoIP phone logs onto the router/server, which looks up the destination and sets up the call. Thereafter, the voice traffic passes directly over the internet between A and B.

Calling a non-VoIP, standard landline or mobile
When A calls B, who has a conventional landline or mobile, the VoIP phone logs on as before. The router/server looks up the destination and finds it is a PSTN (standard) number. The call is routed via the providers PSTN gateway into the PSTN network as a normal call. Thereafter, traffic passes directly via the gateway.

Why use it and who benefits?
Small to medium-sized businesses with several employees, especially those with distributed offices and teleworkers, are likely to get the maximum benefit from VoIP. It cuts your business telephony cost; all calls to other VoIP phone users are free and other calls are usually competitively priced.

You can configure the system to give whatever impression you want to customers. 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 knows whether you have “real” office or a virtual one.

What do you need?
1. A VoIP enabled telephone: This can be an all-in-one handset, or a normal handset plugged into an adaptor, or a softphone: a computer program that uses a microphone and headphones attached to your computer to emulate a real handset.

2. An internet connection: A leased line or ADSL/cable broadband is ideal; dial-up (ISDN or ordinary telephone line) or a satellite internet connection will likely cause a reduction in sound quality and speed. A sgood ADSL connection can accommodate 6-7 simultaneous calls; if you expect to need more frequently, you can upgrade to a higher-bandwidth package.

3. An account with a VoIP service provider: This gives you a VoIP external number which is what other people dial to call you.

Other VoIP related services we offer :-

SIP Trunks
SIP is the latest technology allowing voice calls to be made over the internet. SIP can be used to provide low cost ISDN replacement lines, providing high quality, cost effective telephone lines with the flexibility that comes from using the internet. This service compliments or replaces your existing analogue or ISDN lines connecting to your existing telephone system. Unlike ISDN lines, they can be enabled immediately and provide the same functionality at a substantially lower cost. You can also have any geographic number to suit your business and an unlimited number of lines.

Hosted Phone Server
This provides standard phone system functionality without the requirement for a phone system on your site. The actual phone server (the PBX) runs as a system in the cloud. You can either have a handset on your desk, use a softphone (PC based software phone), or both. This can be a good solution for businesses that do not want a capital outlay for a telephony platform and is suitable for companies of all sizes; start ups, home workers, single site, multi site, etc. Your users can be at any internet connected location; home, mobile or office. They don’t even have to be in the same country.
