Answer a cell phone with Stamp?

Hello
I have succeeded in remote-controlling my RC tank over the phone line,but this relies on a phone line thether within a given household. Now, my circuit also accepts normal tone input, so I can use the headset jack on a cell-phone to control equipment. However, I'm wondering if there are any cell-phone models or functions that will allow a Stamp to detect a ringing·condition and answer it without hardware hacks. I can, of course, tap the vibration motor, but that would involve destroying the phone. Is there any way around this?
Thanks
Rafael

You've got to play the game.
You can't win.
You can't break even, except on a very cold day.
It doesn't get that cold.

I am not sure if I understand your question. I think you are asking how to detect a ringing cell phone without destroying the phone?
I have a Nokia 3220. It will light 4 LED's plus the LCD screen whenever it rings. I would simply use a photoresistor to detect the ringing cell phone.
Build the circuit featured on page 195 of "Robotics with the Boe-Bot". You may have to adjust the values of the resistors used in the circuit as described on page 199. Some example programming code is on page 200. I think that the book is downloadable off the Parallax website.
Here is a pic of my cell phone:
