Have a problem with calling one number out of a G3si 2.0, what is happening whenever we try to call this particular cell phone we get a fastbusy signal. I have had the carrier check to see if they see any problems but they see no problems. We can call other numbers within the same arecode and exchange with no problems just this particular number. So I don't think this is a ARS issue. Does anyone have any sugestion on what I can look for to solve this problem.
