Claim:
1. A method of controlling a codec negotiation of a gateway providing a codec capability offer, for establishing a data connection to a communication device, the method comprising: providing, via a gateway, a Digital Signal Processor (DSP) resource for at least one of encoding data and decoding data to be transmitted using a codec negotiated between the gateway and the communication device; controlling the gateway to limit a selection of codecs available at the gateway to at least two codecs reserving different amounts of the DSP resource, said selection of codecs to be included in a codec capability offer to a codec that reserves a least amount of the DSP resource; forcing the communication device to select the codec that reserves the least amount of the DSP resource; executing the data connection on a channel, wherein a total number of simultaneous channels is limited by the DSP resource; predicting the total number of simultaneous channels by dividing a usable DSP resource by an amount of a DSP resource reserved by the codec that reserves the least amount of the DSP resource; and, if a channel is a used channel, adding the used channel.
