Yes, via the modem from the computer, you can make phone and using FOR a particular call. Really don't like Skype, and full-fare telephone operator. However, forwarding can also be done by the same operator, majority digital telephone exchanges support this service.
If my memory serves me, on some PBX call forwarding can be activated by sending any tones. If they learn and programmed to send out, then maybe something will burn out. It is better for discussion forums to inquire.
