Compliance with the BluetoothTM specification for voice communications imposes limitations on codec types, and the number of simultaneous voice users per access point. The SCO links inherently limit the number of simultaneous voice users on a single access point because of their circuit switched likeness. However, by employing asynchronous connectionless links (ACL) for voice transfer, any codec may be used, and the number of simultaneous users supported by an access point can be increased. These objectives can be accomplished while still remaining compliant to the specification generally, even though other non-specified codecs may be employed.
