Value added services - in particular Voice over Internet Protocol (VoIP) have a big part to play in the future of broadband, according to one expert.
Andrew Ferguson of thinkbroadband has highlighted research from Point Topis which found that value added services in the global broadband industry in 2007 were worth 62 per cent more than in 2006.
Also, VoIP was the service which was found to generate the most revenue.
And Mr Ferguson sees no sign of the VoIP market slowing, even in the face of the current credit crunch.
He said: "VoIP still has some way to go to match the reliability of the traditional telephone network, but the attraction is low cost of calls with people on the same VoIP network often able to call each other for free."
According to Point Topic, value added services are worth $25.7 billion (£14.6 billion) a year to the worldwide broadband market.
