InfoCom estimates 73% of these residential broadband connections will also support a VoIP subscription meaning 87.8 million VoIP subscriptions, i.e. a household penetration of 50%.

The number of residential broadband connections will reach 121 million in Western Europe, i.e. a growth of 88% over June 2007, and will thus mean a household penetration of 68%. InfoCom estimate 73% of these residential broadband connections will also support a VoIP subscription meaning 87.8 million VoIP subscriptions, i.e. a household penetration of 50%. 87.8 million VoIP subscriptions represent 240% growth over the 25.8 million VoIP subscriptions estimated for June 2007. The results derive from infoCom latest VoIP study on 16 Western European countries.

From a geographical point of view, some countries where VoIP is currently not very developed, e.g. Greece or Spain, will outpace others which are already familiar with the service. Other countries, such as France and the Netherlands will not grow quite as fast. The Netherlands might just take over France as the leading VoIP country, at least in terms of penetration, on the strength of its broadband market and the intense competition between the triple play offers of the cable operators and of KPN or other DSL providers. Germany, thanks to bitstream, naked DSL and finally some increasing competition from cable operators should also go.

InfoCom think VoIP is still in the early adopter phase in most countries in Western Europe, although it could be argued, with for instance 33% and 32% household penetration in France and the Netherlands, that it has now passed this stage in some countries and is now entering the mass market. Some recent developments speak rather in favour of VoIP. The attraction of broadband Internet in the first place, with VoIP often bundled with it, most often both with flat rates, should ensure a steady development of VoIP services. So, all in all InfoCom is fairly optimistic about the development of VoIP as illustrated in the forecasts.
