Wholesale?Reseller Account


I have 8port voip termination gateway and I want to use with my already setup Freepbx/A2billing solution as a Wholesale. The scenario is like this, I have FreePBX/A2Billing (which I use for calling card features) and I purchasing trunk for different routes from other providers at the same time I just have bought a TerminationGateway and I want to sell my route to others with the help of my existing setup.

I want to configure my server where I can monitor my wholesale account and want to give my wholesale customers their account where they can manage their accounts.

Please help.
