A solitary broadband connection is all that is needed to make use of Voice over Internet Protocol (VoIP) technology, according to one expert.
Many small businesses appear to be unsure of whether their IT set-up could support the use of VoIP.
But Adrian Walmsley, manager of the British Computer Society's Engineering and Technology Forum, has reassured companies that a standard broadband is all that is needed.
He said: "In the context of a small business with a single site, a single broadband connection is perfectly adequate.
"VoIP routers typically provide QoS - Quality of Service - support which helps to protect the bandwidth needed for conversations while allowing other less time critical functions, such as email, to degrade."
According to a survey carried out by the Communications Management Association, a third of UK businesses say that they currently do not receive satisfactory access to internet technology.
