this service does not allow to call a skype user from a SIP trunk. What they offer is just a regular SIP-to-PSTN service, plus a way for skype users to call into your SIP trunk. I am paying Skype for PSTN calls already. I wouldn't also mind paying them for SIP-to-Skype and Skype-to-SIP (with any public SIP destination) calls if there were such service.
