Phone calls go to voice-mail after 3 rings. How do I change this to the maximum rings before going to voice-mail ? I have the first iPhone. Thank you.

There is a time setting, not a number of rings setting, which is controlled by AT&T at their servers. I believe the time setting limit is 30 seconds. You need to contact AT&T about extending the time setting for your line/account to the maximum allowed/available.
