A method of controlling a codec negotiation of a gateway (1 ) providing a codec capability offer, e.g. OLC according to the standard H.245, for establishing a data connection (1A, NA, 5T, 12T) to a communication device (10), comprises the gateway (1 ) providing a DSP resource (5A, 5B) for encoding (C1 E) and/or decoding (C1 D) of data to be transmitted using a codec which is negotiated between the gateway (1 ) and the communication device (10), and controlling the gateway (1 ) to limit (4B1, 4B2, CA2, CAM) a selection of codecs available at the gateway (1 ) from at least two codecs reserving different amounts of the DSP resource (5A, 5B) respectively, to be included in the codec capability offer to a codec which reserves the least amount of the DSP resource (5A, 5B) such that the communication device (10) is forced (CA4, CA15) to select the codec which reserves the least amount of the DSP resource (5A, 5B). |
