So how do you gauge the success of Call-Net Enterprises Inc. in the local telephony market? The company added about 34,000 new customers in the third-quarter, which brings its subscriber base to about 370,000. It's not a bad number but barely registers when you consider there are about 12 million residential households in Canada. One way of looking at it is Call-Net has plenty of room for growth; another is it is a bit player struggling to establish a viable business. Personally, I think it's interesting that Call-Net is adding real customers while a growing variety of Internet telephony service providers talk the talk. Until Internet telephony emerges from hype to reality in Canada, I'm going to give Call-Net the benefit of the doubt.
