Tieline Demos IP Codec Interoperability Using EBU SIP Standards

SIP-compatible codecs that are registered to SIP servers can dial and connect to other codecs and VoIP devices without knowing their IP address, said PJ Fall, Tieline’s business development manager in Europe.

Tieline Technology said it recently joined eight other codec manufacturers in Munich to test IP interoperability successfully using Session Initiation Protocol (SIP) to connect according to EBU approved standards.

Tieline says that during testing, it demonstrated along with its Dutch-based dealer You/Com that its codecs are SIP-compatible with those from fellow Audio-via-IP Experts Group members Orban/CRL, Mayah Communications and AETA, as well as Prodys, Telos, AEQ, AVT and Digigram.

SIP-compatible codecs that are registered to SIP servers can dial and connect to other codecs and VoIP devices without knowing their IP address, said PJ Fall, Tieline’s business development manager in Europe. “This hugely simplifies remote broadcasting over IP, as there is no need for codecs to acquire static IP addresses in order to connect, even if they move between different locations.”

Fall added that when Tieline codecs connect over IP using SIP, they can exchange information about algorithms, sample rates and connection bit rates. “SIP really is naturally suited to the IP world because of its compatibility with a diverse range of devices, its flexibility and its ability to evolve in the IP environment,” he said.

Tieline codecs connect over POTS, ISDN, X.21, GSM, IP and 3GIP networks using interchangeable plug-in modules tailored to each connection transport.

Additionally, Tieline increased its level of support in Europe by opening an office in Zurich, Switzerland.
