referring to the Wiki, there 4 different builds for voice and SMS support - w/ (or w/o) gsmlib, alsa vs portaudio, etc. i want to test using (A) a mobile phone + USB cable + audio cable and later on, (B) w/ an embedded GSM gateway e.g. Mobigater. will one type of build work in both A and B setups? is there any important item to watch?
