My company is using Sysmaster’s complete turn key solutions starting from IVR up to Billing and we love it. The whole solution has gone very smoothly. We really like the product and can’t complain. Actually, in this business it’s just such an investment that it is hard to find something good before it’s too late.
I would definitely recommend the Sysmaster Billing Solution (Voice Master). We’ve used other ones, and by far the Voice Master has had no problems — no glitches and no accounting errors. Which is important!
p.s. with regards to the routing strength of the device and smoothness of the whole package, we’ve had no problems
