oz list will only work if openzap is loaded, so that's a clue that it isn't for some reason. Try issuing reload mod_openzap from the cli and take a look at the output. There is likely an error on load, and that error may lead you to what's wrong with the config.

Thanks for the tip. Here's what "reload mod_openzap" returns:

BTW, before I investigate further... I notice that the two articles in the wiki about OpenZap are based on Zaptel (1.4), whose development stopped two years ago when Zaptel was replaces with Dadhi: http://wiki.freeswitch.org/wiki/OpenZAP http://wiki.freeswitch.org/wiki/Zaptel_Tutorial Has someone successfully used OpenZap with Dahdi, and if yes, are there any changes that should be made in OpenZap to accomodate this change?

**Module load routine returned an error**

Do you use udev rules? Who owns the dahdi interface, and who does FS run as?

Thanks Joseph for the tip. Indeed, I chowned /usr/local/freeswitch so all files are owned by freeswitch.freeswitch, but I compiled and installed dahdi as root.

The chown business is fine, but who does fs actually run as? Do you use init scripts? # ps aux |grep freeswitch

How do I check file permissions for dahdi? How do I check what udev rules are?

What platform are you on? If you want, use the packages from Atrpms, Axel builds them with a udev patch and Oslec. You need to look in /etc/udev/rules.d/ for something dahdi related: Yours obviously set the interface to be owned by a user/group asterisk. FS can't access them:) See your second post, note the perms for `other`? Edit your dahdi rule to change the owner to whoever runs fs. HTH, jlc

Thanks Tom for the help, but I'm still getting an error when typing "reload mod_openzap" in the Freeswitch console (Actually, two errors: "ozmod_zt.c:Cannot open control device /dev/dahdi/ctl: Permission denied", followed by "zap_io.c failure creating span, no such type 'zt'" which could be a syntax error of mine in openzap.conf and/or openzap.conf.xml).
