I have a Stategy Voice processing Unit that resembles an old desktop computer.
My phone system as you can tell is old but functioning.We have 6 lines. The voice mail constantly needs rebooting to work.
Any suggestions?

now would be a good time to purchase a new system. Contact your local Toshiba dealer you will be suprised on the value and features of a new toshiba system that you could use the same phones you have now but the 5000 phones are cool
