Which term denotes a centralized point for recording switched toll call information?

Explanation:
Centralized Automatic Message Accounting is the system that collects and records toll-call details at a single location. In a toll network, each switch generates accounting records for every switched toll call, and CAMA gathers these records from the switches and forwards them to the billing system, providing a centralized ledger of call duration, trunk usage, and routing. This setup ensures accurate, consolidated billing data across multiple switches. Signaling deals with the control messages used to set up and manage calls, not the recording of toll-call charges; an uninterruptible power supply is just backup power, and Mobile Data Systems relate to data services rather than toll-call accounting.
