Interfacing SIP with Skype
There a couple of ways to connect your VoIP installation to Skype using a proxy application:
- ChanSkype - a Linux application that uses a VNC connection to an X-11 instance to automate the Skype client. A trial license is available. Personal license is US$19 per seat (no technical support available), business license is US$99 per seat (technical support included, limit of 30 seats).
- Uplink - a Windows-based application that installs a virtual sound card to transfer audio to and from Skype. Automation is provided by the Skype APIs. Standard version is free, Pro version is usually US$55 but currently US$38. Differences between versions are unknown and not currently listed on the website. Technical support is available at extra cost. Running Uplink on a Windows box easily allows Skype (both incoming and outgoing calling) to be piped into Asterisk as a SIP trunk.
