asterisk users - Jan 2005 - priority -1

Ho do I pass a call to next priority if call channel return priority -1

To my understanding if I'm in the call and another calls comes the
priority that is return is -1

"Dial returns -1 if the originating channel hangs up, or if the call is
bridged..."

If call channel is busy the priority dial exits with is "0"; so next
priority is executed n+101 (that is easy)

What if the priority is dial returns is "-1" what next?  How to jump
to
next line?
