Just as a point of information, you can compress voice into 4kbit/sec without any real loss of quality.
GSM uses 11.5 kbit/s. GSM is also supposed to provide a digital 9600 bd async connection, but I have not yet seen any implementations of data GSM. Some manufacturers are promising to ship products supporting it during 1993... Julf
