Abstract
Methods, apparatuses and computer programs for selecting a codec for use by a communications device for a session over a network, having a transcoding resource, are provided. It is determined whether the transcoding resource is available for the communications session and, if the transcoding resource is available, a subset of codecs available to the communications device is used in a signalling process used to determine a codec for the session. The subset is selected based on an operative condition affecting the communications device.
