That's a funny way of doing:

/bin/chmod 0660 /dev/zap/*
/bin/chown asterisk:asterisk /dev/zap

And anyway, assuming you use udev, the best way is to create those nodes
with proper permissions in the first place.

* They must not be world readable, because even opening a device for
  reading by a randim user has potentially bad results.
* I'm not sure about your distribution. In Debian files under /dev seem
  to be created with 0660 permissions by default (r/w to user and
  group, notihg to others). I can't find exactly where this is
  documented to be the default.

Hence the sole rule in the current Debian config that deals with
permissions is:

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

If I'd wat to aplpy all of your explicit configuration:

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

Make sure you have that line in your udev rules in the proper place.

What distribution do you use, anyway?
