Provider Billing Addon
Description
Provider billing addon allows reversed billing - it counts provider's balance which increases when admin or reseller makes a call through it.
This add-on can be used in the following cases:
- Provider sends you a bill/ invoice for the calls and you can check if it is correct. Amount shown in Provider billing section should match the invoice from your provider (this can be applied in all VoIP business models where you use some voice traffic suppliers).
- Provider is your client and supplier. In the end of the month according to bilateral agreements you just check the overall balance (this is usually applied in VoIP Wholesale business).
- If you use GSM gateways for termination, adding the time limit per day allows you to avoid clients hearing that the SIM card balance expired as MOR automatically routes the call to the next available GSM gateway (this is used in VoIP Termination business using GSM gateways/SIM banks)
Balances
Provider has balance which increases when call goes over this Provider. E.g. Provider receives money for the calls over him.
If Provider is assigned to the User then such Provider can make calls. When Provider (which is assigned to the User) makes calls, such calls goes over other Providers and User's (to which Provider is assigned) balance is decreased.
IMPORTANT! Provider's balance and User's balance are two different values. They are not connected and do not impact each other. They change independently of each other.
