Abstract
The invention proposes several methods for codec handling. In specific, methods involving providing a supported codec list of a Call Control Server are described. A node receives information, whether a terminal supports a wideband codec, wherein the information is received in call set up signaling from the terminal of the subscriber. Furthermore, configuration information is retrieved, whether a Radio Access Node supports the wideband codec. Additionally, information is retrieved, whether a media gateway supports the wideband codec, wherein the information is either provided by the operator or retrieved from the media gateway (MGW1, MGW2, MGWx). The information is analyzed and in response to the analysis a supported codec list is provided. Furthermore, alternative embodiments and devices adapted for the methods are disclosed.
