OpenSER supports H.350 identity management for VoIP

OpenSER, a leading open-source software solution for Internet protocol (IP) telephony infrastructure, now supports identity management and directory services for voice over Internet protocol (VoIP) through H.350 components developed by Information Technology Services at the University of North Carolina at Chapel Hill.

ITS at Carolina has released modules for OpenSER that allow the IP telephony server to access an enterprise directory for user data (such as user ID and password validation). H.350 has already been adopted by many leading IP communications companies, but its addition to a leading open-source solution will push the technology into thousands of deployments worldwide.

“There is a growing demand for IP telephony solutions that can scale to hundreds of thousands of users,” said Christian Schlatter, ITS network architect at Carolina. “The security, financial and enterprise markets are demanding H.350 in order to make their networks manageable and secure.”

The H.350 architecture allows enterprises and carriers to directory-enable communications technologies so that large numbers of users can be more easily managed. Groups will not have to have separate passwords for IM, e-mail, VoIP telephony and video chat – all of a user’s varied devices can be managed under one account stored in a single directory and managed by a unified identity management system. ITS at Carolina has been collaborating with research and standards organizations around the world for several years to develop Real-Time Communications (RTC) technologies of which H.350 is a key component.
