I am Looking to have a systems setup for a multi-tenant VOIP system with load balancing and redundancy. Also to have an astpp package setup with sample customers and the ability to do monthly billing through my credit card processor at a set monthly rate.
It is very similar to the document "Load Balancing of network" that is posted in your portfolio at this site.
As of now I believe that I would have 1 opensips server and 3 freeswitch/fusionpbx or Kazoo servers with a common database on one of the freeswitch media server.
I would have the servers setup and running CentOS 6.5 with a shell account for you to access.
I was wondering if you could give me an estimate of the cost for a project of this nature. I am also curious what cost would be for ongoing periodic installation and configuration of newly added systems and systems that we as a company choose to replace.
