PortaBilling can collect information about calls in progress from the PortaSIP server, Cisco/Quintum gateways and other VoIP nodes. The only thing required on the VoIP node side is the capability to send Start accounting records, in addition to Stop records.
This enables several options:
- You may see a list of calls in progress on the PortaBilling web interface.
- You may forcibly disconnect a specific call (if the call is routed via PortaSIP).
- You may specify the maximum allowed number of simultaneous calls for each customer. PortaBilling will reject any call attempts above the allowed number of concurrent calls.
