[asterisk-users] OT: Samsung Sprint CDMAoIP

[Paul]

Does it switch back to wifi from gsm tower? If so, I would hope they
count total gsm seconds for the call to determine how many minutes get
deducted from the wireless plan. Otherwise, somebody could get clipped a
full minute for every time he leaned out the window to yell at the kids.
