3 way calling

my dad had surgery today..out patient but surgery. he called my cell phone and we chatted a bit. he is doing well, thanks, but then my son wanted to talk to him. we put the cell phone on speaker phone. while my son is talking to his Grampy, the land line rings. it is my nephew calling to talk to my son. I tell him that he is talking to Grampy on the cell phone. G laughs and says he just tried calling Grampy himself. so this is what we did...we put the land line on speaker phone, too. here is a photo of a three way call using two phones...the callers on both phones live in one state and we live in a third. it was so funny to hear my Dad and my nephew talk while both on speaker phone. gotta love those boys!
