Nortel Networks last week demonstrated in Hong Kong its Voice over Internet Protocol (VoIP) product line, called Succession, which is being tested by some Asia-Pacific carriers. The Canadian company, one of the world's largest makers of telecommunications gear, sells switching and routing infrastructure based on the new Session Initiation Protocol standard, Lydia Zajc reports. The product line allows consumers and business customers to use video on phone calls, pull up information on callers, and other operations on computers and Internet phones. The global economic downturn has caused companies to freeze tech spending, but companies such as Nortel are hoping cutting-edge technology products can bolster sales. Nortel, listed on the New York Stock Exchange and other exchanges, plans to bring the Succession line to the Hong Kong and Asia-Pacific markets once it is generally available in January. 'We will have contracts we will announce over the next many months,' said Asia-Pacific vice-president Enis Erkel, who is in charge of the product.
