I worked on one of these https://www.talkswitch.com/us/en/Products/ today. The customer bought it himself and called and asked if we would install it for him. I mounted it on the wall, connected the phones and lines, plugged it into the LAN. He then connected to it with his computer and off he went. Literally that was it. Pretty slick and from the little I saw of the programming, there were many valuable features. I was on site for two hours and then I left thinking. This is a dyeing industry. If a customer can buy it and program it himself who needs me. If he had the tools he probably wouldn't have called.

Anyone else work on this product before?
