cell phone to land line

[medfield]

I have been searching google all day long looking for a solution for a possible christmas gift. What I am trying to find out is how do I create my own docking station for a cell phone.
My brother has an LG vx4500

and I am trying to connect it to a Homer Simpson phone (!!!)

I know they make docking stations online, like the dock-n-talk or cidco merge. But what I really want to try and do is make the connector myself, because I like to learn things I just dont understand. It really shouldnt be that hard, figure I would ask around online for some tips.

I know sparkfun had an article for a rotary phone

but that just seemed way more complicated than it needs to be, because with the rotary you need to decode the sequence and some other shit, but with a tone you just need to make sure the sound gets processed correct? I might be out of my league but im a quick learner if I get pushed in the right direction. Aint no way I am spending $130 for some shit unless I have exhausted all of my options

Any response would be gratefully appreciated

I know you are allllllllllllllll wondering about it....but I figure since no one responds I found the answer anyway. I just need to hook up a car adapter (which also communicates by serial commands), then using a datascope I need to record the serial commands for the different functions, as buttons are pressed and the phones are used.

Once I have the datastream figured out (BLEH), Ill try to connect the four wire audio from a cell phone to the two wires on a regular phone, using sopme hybrid transformer (and somehow avoiding echo). I found out its a lot more work than hooking up a few wires, should be interesting...or maybe ill just buy the damn thing afterall
