Also remember that EDGE, UMTS. HSDPA, and LTE are all to do with data speeds, not voice.
Not entirely true.
UMTS is essentially another term for W-CDMA. (GSM adherents oft prefer to refer to UMTS, perhaps because they resent that it is actually a form of CDMA.) Regardless, UMTS/W-CDMA most definitely carries standard circuit switched voice traffic.
