Canadian businesses lag their international counterparts in VoIP implementations, according to a study from AT&T Inc. and the Economist Intelligence Unit. While nearly half of companies around the globe have installed IP voice systems, just 37% of Canadians have done so. However, Canadians seem to have more sophisticated attitudes toward IP: 79% said the technology’s key benefit is better collaboration with customers and suppliers, whereas the global average was 70%. IP equipment sellers largely consider productivity improvement measures as more sophisticated than service-cost comparisons.
