I’d like to add my boot to the sysmaster bashing. I have nearly 15 years experience in the Internet industry, and a few in VOIP. Sysmaster have the worst attitude to customer service I have ever encountered. Somewhere between malicious and apathetic. I have dealt closely with many hardware and software providers over the last decade, and sysmaster have very clearly distingushed themselves as the absolute worst.
We used them primarily as a h323 besed calling card platform. It is almost embarassing to think of what chosing voicemaster has cost us in lost revenue and lost business. We are currently desperate to move away, but because of the extent we have depended on them this is proving very difficult.
I can certainly understand why people would want to sue them.
I should point out I am not assoiciated with any voip hardware / software vendors, just AFIK, a typical sysmaster customer. Over a barrel, and desperate to get off.
