one application inside browsers -- a development mirrored by ongoing IETF new standards work on real-time Web communication -- the engineering community urgently needs to address open challenges of Internet Protocol-based telephony, speakers said at the conference here. There are some things to keep from POTS, like availability regardless of geography, income and disability, and also some security features, Schulzrinne said. Conversations traveling over the old phone system had relatively strong privacy protection, which isn’t true for Internet conversations, he said. Availability and quality issues of IP-telephony had to be addressed, he said. “We as a community need to grow up.” Schulzrinne was a regular contributor to the IETF before becoming FCC CTO in 2011 (http://fcc.us/X3Soca). “We were used to having a second network to call our provider if the Internet did not work,” he said. Other issues the FCC is concerned about are reliability of emergency call channels, he said. The agency will start open consultations of its Technology Transitions Policy Task Force on Monday, he noted. Asked if regulatory steps were in the basket of the task force’s work, Schulzrinne said the commission is looking for an analysis of changes so far from copper to fiber, from fixed network to mobile and from circuit to packet switched technology. He said he hopes the IETF community steps up and tackles open issues.
