asterisk users - Jun 2005 - Phantom (ghost) Calls with Wildcard TDM400P

We have a client that has a single Wildcard TDM400P with 3 FXO ports on
Asterisk 1.0.7.

Occasionally the system seems to loose its mind and starts originating
calls from that Zap channels that don't exist. The receptionist picks up
the phone and nobody is there. This can happen repeatedly over and over
again within a few minutes.

As far as we can tell these are definitely not real calls as nobody has
ever called back and said they couldn't get through.

Does anyone have a suggestion for why this might be happening?

Is there an alarm system, fax or any other sharing the line?
