[Asterisk-Users] restricting access to outside calls

[Ed DeHart]

When you call my system your call is handled by the auto
attendant.  It works fine with one little problem.  In addition
to being able to dial any extension during the announcement, you
can dial a telephone number.  The system will bridge the Zap
channel I call in on with another Zap channel and dial the number.
This allows anyone in the world to make calls to anywhere in the
world via my system.

While this is fine for extensions logged into my system.  It
is not good to allow unknown users to make calls via my system.
How can I restrict access to connected users only?

Thanks for putting up with a post from a newbie.
