Hi FMP
We are a user / supplier of the VoiceMaster product and have been running our own very successfully for the last six months. Without a doubt it is one of the most comprehensive billing packages on the market and has additional modules (that can be purchased) to cover most scenarios – from wholesale to corporate to calling card to phone shop etc.
Unfortunatley Sysmasters support isn’t the greatest and they are based on the West Coast of the US, so unless you are in their time zone it can be frustrating waiting for support to get back to you.
The best method is to buy from a local dealer or someone who offers 24/7/365 support on these products. Then you get the best of both worlds.
If you would like some more information please feel free to contact me at: mhitchcock@blue-lava.co.uk
Hope this helps.
Mat.
