ABSTRACT:
The invention is related to a method for transmitting data in a telecommunications network and a device, e.g. a network node, utilizing that method, where said data transfer requires the application of algorithms for coding and/or decoding (“codec”) on said data, where at least one of said network nodes provides a list (25) of available codecs and transmits it to a further network node, where said further network node chooses from the received list (25) and from a corresponding set of codecs available to the further network node a combination of codecs to be used when transferring said data, and where the received list (25) not only comprises direct codecs (28) but transcoding codecs (29), i.e. codecs requiring transcoding, as well.
