ICTPBX includes a built-in billing engine that tracks your resource usage, enforces package limits, deducts credit for calls and faxes above your free-tier quota, and shows you a live dashboard of what you’ve used and what you have left. Billing is part of the Service Provider Edition. Super Admins, Tenant Admins and End Users can all see it.

Checking Your Usage
Go to Billing › Quota to see your slot limits for PBX resources (extensions, devices, ring groups, call queues) and the voice minutes, fax pages and conference minutes your package includes free each month. Billing › Usage shows what you’ve used and what it cost in each period. End users see My Quota and My Usage instead.


How Billing Works
- Resource Packages – your Super Admin assigns your tenant a service package that sets slot limits for extensions, devices, queues, and other resources, plus the voice minutes, fax pages and conference minutes included free each month
- Usage Above Free Tier – once you use your free minutes or fax pages, additional usage is charged against your credit balance at your rates. Usage is processed every hour.
- Monthly Reset – your free allowances reset every month
- Zero Credit – calls aren’t cut off automatically when your credit reaches zero. Your tenant can have a max concurrent calls limit and a low-credit email alert.
- Slot Enforcement – when you hit a resource limit, ICTPBX blocks creation of that resource type and shows a clear error message. Slot limits are hard limits, unlike the free minutes and pages.
Credit Balance
Your current credit balance shows in the portal header and updates every 10 seconds. When your balance runs low, contact your service provider to add credit. Payments appear in your billing history immediately.
