摘要

An apparatus, method, system and computer program product is configured for optimizing usage of bandwidth extension. Codecs to be used in a communication connection between communication network nodes are negotiated, wherein the negotiating comprises indicating a capability of a communication network node to expand bandwidth by indicating support of the communication network node for a wideband codec towards another communication network node; and lacking codec transparency for the wideband codec at the communication network node are indicated.
