I have a customer who lost access to there TVS220 voice mail. I went onsite to troubleshoot and found the power light blinking. I power cycled the voice mail with no result. Has the 220 failed or is there anything I can do?

Check the ports, are they still vm dpits ports?
Do they work, try others!
Does the 220 talk to a Term.

is the hard drive making noise, like something loose, or sounds like it tring to start, but keeps making the same clunking noise

is the light flashing steady or 3 flashes, stop then 3 flashes and so on

The light is blinking at a constant rate with no pattern. The customer said that it starting working again for a day and then went out once again. I can't hear any noise coming from the equipment.
