About 73% of Canadian businesses plan to integrate their mobile voice and data services with the enterprise IP network, according to a survey from AT&T and the Economist Intelligence Unit. The findings put Canadians on par with their global counterparts – the worldwide average is 72%. Technology acquisition costs and deployment challenges are the biggest hurdles in this country, according to AT&T. But only 45% of Canadian firms have a clear mobile-IP integration strategy, compared to 76% in the US. Mobile-IP integration extends office-based communication functions such as directory dialing and single-number reach to mobile devices.
