At some times I need to work from home and I'd like to use my office extension number to answer calls the way I would when at the office.
Is it possible to somehow configure the soft client to get this functionality?

If you have a VPN in place at home you can connect in the same way you do in office.
If you do not have a VPN you should setup the 3CX VOIP Client to use the Tunnel. The various modes you can used are explained in http://www.3cx.com/user-manual/Updated link.
