   If the signal is sent via RS232 (Your typical com port) it's easy to 
make a cable that does this.

Been a while but if you post the make/model number of the phone (FCC ID is a 
BIG help) I may be able to find my notes from back when on how this might be 
accomplished.  If it's old enough I may have some of the hardware in a box. 
(did I mention ... once upon a time I designed cell phones?)

I don't think the protocol will let you do that.
But for grins, here is a related but irrelevant link.

I have serial splitters :)  I need a USB splitter!  Well, I want one, 
anyway.  Since I know what signals I'm sending maybe I can cob (cobb?)
