"VoIP certainly looks inevitable. User surveys put the number of organisations in the UK using IP telephony seriously at between 25% and 40% - with an expected increase to 85% to 90% in the next two years. Indeed, voice services are by far the main reason behind organisations moving towards converged IP networks, according to the latest annual survey by the Communications Management Association (CMA). It found that 60% of managers cited VoIP as the primary reason for network convergence. In a separate question, 73% said VoIP was a key element of their collaboration strategy - up from 63% last year."
