Well, not really. GMSK is the modulation technique on the RF signal over the air. We extract the data stream out of the GMSK signal to create a digital signal that contains the D-STAR frames (including headers, etc.). Inside the D-STAR digital voice frames, is the AMBE vocoder data stream that actually contains the digitally encoded voice that becomes the voice portion of VOIP. One could argue it is D-STAR over IP (DOIP - Do IP) as there is more to the protocol than simply encapsulating a codec (like GSM or uLaw). If we digitized the GMSK signal and sent that over IP, you might call it GOIP (Go IP), but as it is now that would be a misnomer. -- John, K7VE
