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.

3331.2.7.1 Hard Crash

by cwible, Wednesday 10 of May, 2006 [15:43:12 UTC]
We have been using chan_skinny since 1.0.9 for almost a year with no issues. We then upgraded to 1.2.7.1 and realized that Asterisk would core-dump after several skinny registrations. Removing the module solved the problem. We're not entirely sure why, but there appear to be a few bug reports in Asterisk's Mantis database that reference this issue and it doesn't appear that it will be fixed any time soon.

If you really need to use chan_skinny and upgrade, run an older version of asterisk for the skinny devices and a separate version of asterisk for the main phone system and use IAX between the servers or try chan_sccp.
