I've followed the instructions located at: http://www.cesnet.cz/doc/techzpravy/2006/asterisk-ss7/ Specifically section 6. I started off with a fresh TrixBox 2.0 install (i know, but this is what it needs to be..) updating using svn as explained the link above. Whenever I start asterisk, I don't see any options for ss7. Is there something I'm completely missing here? I've got 1 span configured in zaptel and ztcfg -vv comes up with no errors. Asterisk starts fine, but pri/zap/ss7 is not available as an option in the CLI. If this is familiar to anyone else, I'd love to know that I'm not alone. :)
