I'm trying to get through to my doctor's office, and the system is busy. I dial over and over and over and it's still busy (this happens a lot). Is there any way to change my Obi 202's settings so that when it's no longer busy, I get a call back from that number? I vaguely remember my parents having a service like this years ago when I was a kid/teenager. I'm not sure if this can be achieved with the Obi, or if this is something that has to be supported by FreePhoneLine (who is my provider). Or maybe Google Voice? (I have them too)
