First, GSM is a speech codec. GPS is a satellite-based locating system. You can't require VOIP to have GPS because VOIP doesn't require any specialized hardware beyond a microphone and speaker and appropriate ADC/DACs. You can have a VOIP phone implemented in software on a laptop, or a PDA, or your mother's Windows box. Second, the price of a hardware VOIP interface is down to $40 and falling, whereas the cheapest GPS unit I'm aware of runs $90 or so. Third, the term "VOIP" covers two or three dozen implementations of a dozen or more protocols. -dsr-
