I’ve worked a little on Asterisk and have a bit of interest on getting Chan-SCCP working so a Cisco 79XX series IP phone will run natively with it as a very cost affective VoIP Pbx.
I’ve put together a small howto on the initial configuration steps that are recommended (primarily for myself so I don’t have to re-learn it the next time I build one!) for both security and the inclusion (compiling) of the current release of Chan-SCCP (which is at V3-RC3 as I write).
Attached is the Howto and some sample configuration files for Asterisk.
