Long time ago I posted about the support service at sysmaster, it was not good at that time, now is way much better, business perspective on every company change and I am a guy that likes the challenge so I trained on Norfa services, also trained on asterisk and trained alot on gatekeepers, with the time I could find the source of my problems with Voicemaster and I can tell you that it was mostly IGNORANCE, Yes I install Norfa services as a third party consultant not related to Sysmaster, yes Norfa is based on Voicemaster with way more functionality and database integration and new hardware.
