CC Proxy can work as SOCKS proxy server for Voice/Video Chat software.

CCProxy is an easy-to-use proxy server software. Full supports Windows 98/ME/NT/2000/XP. For more details of CCProxy, please click here. Also you can download it here for a trial.

Most voice chat software doesn't support proxy such as MSN and Yahoo. You need to install SocksCap32 at client, add voice chat software into SocksCap32 and launch it from SocksCap32.
For specific guide, please refer to http://www.youngzsoft.net/sockscap/. Currently CCProxy cannot support MSN and Yahoo voice/video chat. If you want to use voice/video chat, we suggest you use skype. In skype, the Internet Explorer proxy settings are used.

If you are using Skype, Skype supports SOCKS5. You can set up SOCKS5 in Skype's connection settings. We strongly suggest you use Skype's voice and video chat instead of other video chat software.
