The Reseller module

The general information:

Resellers system consists maximum of three levels. Resellers added in the Resellers I section constitute the lowest level. Resellers of that type can create clients accounts and tariffs. Second level resellers, Resellers II, cannot create accounts in the VoipSwitch system. They have the possibility of creating First Level Resellers’ accounts and tariffs, used afterward for first level resellers. Identical situation refers to Third level resellers. They can only create accounts of the Second Level reseller and the corresponding tariffs. They cannot create First level resellers’ accounts and VoipSwith’s clients.

Resellers of the First and Second levels can be assigned to the higher level. Execution of the call by the client, assigned to the First Level Reseller, results in reducing the reseller’s call limits by the cost of the call. Cost of the call, for the First Level Reseller, is calculated based on the base tariff assigned the reseller. This tariff is assigned by the higher level reseller or the VoipSwith’s system owner. 
If the reseller of the First Level were created by the Second Level Reseller then the amount of such a call is also deducted from the Second Level Reseller’s call limits. Cost of such a call, for the Second Level Reseller, is calculated based on the tariff assigned to the Second Level Reseller.
The identical situation applies if the Second Level Reseller were created by the Third Level Reseller.
In case there is a zero or negative amount on any level reseller’s call limits, the call will not be able to be executed by the VoipSwith’s client. Thus, is crucial for each level reseller to check calls limits amount regularly.
