2.5mm TRS -> 2x 3.5mm TRS?

Here's my problem:

I'd like to connect a mobile phone to the pc in such way that I can playback/record sound using the pc. So I need to be able to receive and send sound data from a phone call using PC.

This would allow to use PC to record phone calls and detect DTMFs, and also playback DTMFs and voice data. Very handy for many purposes.

I can think of two possible solutions:

1) Use some kind of adapter that converts phone's 2.5mm dual-channel mono (in, out) to two 3.5mm stereo cables that connect to pc's in/out audio ports. Do ready-made adapters and cables exist for this or do I need to hand-craft this?

2) Use bluetooth connectivity. What software and hardware I need to achieve this? How much latency does wireless approach cause?

Thank you in advance.
