Call stopped after 2 rings. Caller ID was AA. Same caller ID was shown for 510-671-8305 on 8/9/16 and also stopped after 2 rings. If AA stands for A** holes Anonymous I would answer and try to help them quit.
Daily calls from ,Caller ID says AA, no message is ever left. I have, disconnected, SIT tones on my outgoing message, and this caller continues to call.
