I bought a sysmaster voicemaster 3 years ago and now it doesn’t work. I was disappointed with the support, but I looked deep and realized, if you understand how VOIP works you should realize that Sysmaster is a billing platform/radius server. Not a softswitch. It is not an out of the box solution to make millions unless you know how to add the necessary components. (you got the documentation…Right?) If you are not Voip saavy, or don’t know how to configure dial peers in a cisco router, that’s on you, don’t expect this to be the catch all be all, with no work on your end. You really need to understand radius and ip port triggering. Once you take the load off of the system it does what it is supposed to do. It is a system billing manager not a work horse. When you drive a car does the power come from the gauges on the dashbord or from the engine under the hood? Only a fool would think that a 1U device is the answer to all of his telecom needs. They pretty much spell it out, but you need to read between the lines. If you are technically smart you should read the documentation and take advantage of the insight they provide. I have learned so much about voip, radius, and server applications, it’s unreal. I admire these folks because all they did was put together a sound billing, and accounting platform. ( for anything) It’s up to you to expound on it. I will admit support has it’s moments. And yes they might sell you something you can get elsewhere, or don’t need but if you are in the business don’t piss and moan because some company can take advantage of you because you don’t know what the F*&^ you are doing. Yeah you can get asterisk but can you setup the tables or put the GUI interface to it. The big boys use Nextone or Mind but they have the continuous big PC( Microsoft) issues that require maintenance on top of maintenance agreements with I have a partner that pays $3000.00 for per switch each month (Excel switches) running Rubix, and he was getting his VoIP billing from my sysmaster. I’m not swinging on their nuts,… and I must admit I have some pending issues but realistically when you look at it what else can you buy a total solution that isn’t tied up with some windows BS for 25 grand. The bottom line is you cannot beat the database views. That is where the true expertise is. I have worked with sonus, santera, nokia, alcatel, cisco and lucent and none of them have presented the ease of use, for everything like sysmaster. But I must admit sysmaster resembles the attributes from a few open source applications that none of us can afford or that we are not willing to develop ourselves. Bottom Line Voicemaster is a billing manager, not a call processor, or a switch or softswitch. Once you realize that you will be good to go.
