Well Saul, all I can say from my point of view and experience with these people is that I was a costumer of them for 3 weeks, because as soon as we got the Voice Master we found out that the product didn´t have all the features we asked for, after we told them that the system didn´t do this or that (we had asked for all the features in writing and also we told the sales person the same when we went to their offices in San Jose CA) they told us that if we wanted to do all of that then we would have to buy several extra modules (they have like 50 or more)in order to achieve that. That meant that we would have to pay more that the DOUBLE!!! of the price that we initially paid!!!… (it sounded like a cartoon comic to me). On top of that we wanted to do IP to IP devices calls and we initially had told the that we wanted them to be PEER TO PEER (no bandwidth consumption from our side), of course at the sales point they said “YES WE DO THAT”, but after we bought they told us “THAT IS IMPOSSIBLE TO DO IF YOU ARE BEHIND A NAT ON BOTH SIDES”, but there are companies (LIKE JASOMI) that do that already and very succesfully. At the end we returned the server after 2/3 weeks and they had to give us our money back (they took $200 off and I had to pay like $250 for shipping). In summary I wouldn´t recommend anyone to buy products from this company, not one!!! be carefull with these people. BAD support and not serious way to do business.
