VoiceMaster is a very good product. but my only feedback and opinion is about the company itself (sysmaster). their only problem is the customer service. They have technical people who don’t really know their products. You can spend 30 min on the phone and at the end they till u to write an email and then they’ll reply to you. not only the technical people, even their sales people. It takes them more than a week to reply to a future customer who wants more info or looking for a demo. other than that the product is very good.
