I agree with Teodor on this. I have been in the telecomm business for over 20 years and I have never seen anything like the customers who want to start using VoIP. For the most part these people are highly uninformed people who know nothing of VoIP or Telecom and want to start up a business with it because someone told them it was easy to do.
They all want the equipment for the cheapest they can possibly get (that is why they buy it on ebay and on the used market) and they all need support because they do not have the technical know how and they want it for free from the manufacturer.
They never stop and think that most manufacturers make little money on selling equipment, but they try to make up the money on support.
If these companies were to just give support away for free, then they would not be around for much longer.
