Abstract

Verfahren zur Codec-Verhandlung zwischen zwei Gateway-Controllern (25, 28), wobei die Gateway-Controller verbindungsunabhängig eine Codec-Liste mit Codec-Typen verwalten, die von dem jeweiligen Media-Gateway (24, 27) unterstützt werden, so daß ein späterer Abbruch einer aufgebauten Verbindung aufgrund nicht unterstützter Codecs vermieden wird.
