Consumers know a good deal about service providers more than the service providers, about consumers. Consumers politely bore the high rates they were being charged for the telephone services, prior to VoIP. Even after VoIP was introduced, they know pretty well that they are getting this high quality service at affordable rates only because of the competition that prevails among the VoIP providers. But they need not be worried if these rates will continue because this competition is likely to extend and is likely to get these consumers several additional features also because the best voip providers have already started investing millions of dollars on research to bring out such features.
