This morning mom called and I missed her call for being on potty break. Well the thing is, I tried calling her back on the cell phone and it rang with no one answering. Then, I called the house and she answered..The weird thing is that I tell her where she was and she replies 'Burleson' (which is the next town)..I was but mom, I'm calling you at home and you are in the next town??I really don't get it since it has never happened before..maybe she was still on the line from the first time she called?

Could be call forwarding, or multi phone ring.
