IP Codec Interoperability via SIP Demonstrated

March 5, 2008

Munich, Germany - Feb 29, 2008 - Audio-via-IP Experts Group members Tieline Technology, Orban/CRL, Mayah Communications, AETA, Prodys, Telos, AEQ, AVT and Digigram met in Munich from Feb 11 - 13 to test IP Interoperability using Session Initiation Protocol (SIP) to connect according to EBU-approved standards.

PJ Fall, Tieline business development manager in Europe, explained that SIP-compatible codecs that are registered to SIP servers can dial and connect to other codecs and VoIP devices without knowing the IP address of the receiving unit. This simplifies remote broadcasting over IP because there is no need for codecs to acquire static IP addresses in order to connect - even if they move between different locations.

Lars Jonsson of Swedish Radio acting on behalf of the EBU thanked manufacturers their work to prepare the successful meeting, despite the different commercial interests. "On behalf of all the EBU-team, I would like to thank you very much for the hard job you all did in Munich. I was so impressed to see you all work together over company and country borders so patiently to solve all small details in good spirit."

When IP codecs connect via SIP, they exchange information about coding algorithms, sample rates and connection bit-rates.
