If you use Skype then the simplest solution is to run it on a separate
PC using the built-in soundcard (this usually works). You then have to 
connect that PC's headphone output to your main soundcard input (this may
require a DI-box to get a clean signal) and the main soundard line out to
the mic input of the PC (which will require a passive attenuator and maybe
also transforer isolation).

It is in theory possible to run Skype on the main PC and connect it to
jack using snd_aloop, zita-a2j and zita-j2a. It's not a stable setup
(Skype being very fussy about sound cards), so I wouldn't recommend
doing that.
