Have you tried running defrag on the VM?? I bought a new butt set the other day because I hadn't had any neat new toys for awhile. It is the LIL'BUTTIE RANGER by U Test-Um, Model LB255. In monitor mode it will detect and display all 16 DTMF tones being dialed on the CO line. Alot easier than transporting my other digit grabber toy around. With problems like this I always ask myself, what happened and what changed to make it stop working?
