Also not a 3Com person, but I know how to spell it.
Does the 3Com have any logs? You may want to set up a machine to collect SMDR (if possible) an have ALL extensions output to it (Some systems you can exclude SMDR output on an extension by extension basis)

The Spoofing brings up an interesting point.I wonder how the destination knows how to bill for the calls? I assume the phone company does it, but does the phone company truly know where the call originates. or does it xreference the BTN it recieves.

IS the VM in the same COS the other stations are in?
