Fred Donovan of Fierce Enterprise Communications sat down at CES with AT&T vice president of regulatory affairs Hank Hultquist to talk about the company’s plan to transition to an all-IP network. On what the transition will mean for voice communication:

Voice quality is a “perceived obstacle,” Hultquist told FierceEnterpriseCommunications. “I think that perception will change quickly because of the introduction of voice over IP on the mobile side… which will evolve pretty quickly to high-definition voice. High-definition voice has a much wider range of sound, and the voice quality is going to be substantially better than what people have had before.”

“When HD voice over LTE takes off, going forward voice over IP in the enterprise will get much better than the traditional switched voice experience. When that happens, the perceived obstacle will vanish,” he added.

Hultquist also discussed the challenges of maintaining the legacy network of the past:

The telephone network we all grew up with is now an obsolete platform… that will not be sustainable for the indefinite future. No one is making this network technology any more. It will become increasingly difficult to find spare parts for it. And it is becoming more and more difficult to find trained technicians and engineers to work on it,” Hultquist explained.

“This is a very practical problem. How do we retire this legacy network technology and move into this all-IP world?” he added.
