I agree with Embittered Alfie. If you want to through your money away, then buy a VoiceMaster. We have one now for over 2 years. Their Tech Support doesn’t know zip all. Boris Panteleev, the owner is the most arrogant person I have ever come in contact with. When you have a problem, the first thing he rights is that YOUR configuration is wrong. They change things in their upgrades version over version without tell you. At the end of the month, you notice that you lost lots of money without them taking the responsibility. Don’t buy VoiceMaster.
