I have been a customer of SYSMASTER for two years. I am reading all your posts on Sysmaster. For those planning on buying their stuff I have one advice DON’T.
Here are the issues: Open source software without full disclosure, t heir gateways use software compression and not DSP like Cisco’s therefore causing the system to drop calls when 1/2 capacity is reached, There sales people overhype their products, They hold the root and sa passwords to your systems and their support people will come in to your system and make modifications without your knowledge or permission. Their capacity is overstated by their sales people they can not even handle 1/4 of the minutes.
