chan_skinny is an asterisk module handling the skinny protocol, to connect natively to the cisco 7900 Series phones. Some of them do not support other voice protocols.

chan_skinny is included in the asterisk distribution, whereas some other modules are available from other projects.

Configuring chan_skinny

The config file is not to complicated, but the problem with skinny phones is most of the time to "boot" them. They expect some DHCP options & some tftp files.
