Please see README.udev of zaptel.

Basically, those files are generated by udev. You might as well tell
udev to chown them to asterisk.asterisk (or root.dialout, the standard
on Debian systems)


The default permissions.rules file on Debian Etch now contains:

SUBSYSTEM=="zaptel",                            GROUP="dialout"

A more complete rule would be:


But you may choose to use:

SUBSYSTEM=="zaptel", MODE="0660", USER="asterisk", GROUP="asterisk"


BTW: that line is missing from the udev package in Debian Sarge, leading
to a similar problem to the one described here once the uder decides to
use udev.
