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 (!!!)
**broken link removed**

I know they make docking stations online, such as the dock-n-talk or cidco
merge. But what I really want to try and do is make the what seems to be simple connector myself, it really shouldnt be that hard, figure I would ask around
online for some tips. Im feeling the electronic fever since I put some
life back into my ti99

I know sparkfun had an article for a rotary phone
**broken link removed**
but that just seemed way more complicated than it needs to be, because
with the rotary you need to decode the sequence then convert it to a
tone, 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

Any response would be gratefully appreciated

This is not an easy task. You need to get pin out information and protocol information on the phone in question to even begin. Most phone's have the ability to be connected to a base station like an in car speaker phone, which is exactly what you want, but that doesn't garuntee that the phone has the ability to be communicated with (to intiate dialing and answering) Getting this information from the manufactor of the phone will be difficult if not impossible (they don't generally give that kind of information to the public) But really I don't see any reason why you couldn't home brew something that would work.
