How to connect sound-card mic/spk to telephone's handset?

[kingsz1]

Hi, Help me please if you get any idea.
I want to connect the sound card input and output to a normally telephone's handset(only handset!), so the input for sound card MIC should from handset's mic, and the output from sound card SPK will go to handset's earphone. How can I do that?

Does your phone have a jack on it for a headset? I would think it would. But, if it doesn't, then tell me and we'll go from there. :wink:

It is handset, no headset!
