The correct answer is CAMA, which stands for Centralized Automatic Message Accounting. CAMA technology is used within telecommunications systems to collect Automatic Number Identification (ANI) information. It serves as a centralized hub that not only registers call duration but also efficiently routes calls based on the collected data. This functionality is crucial for emergency services, ensuring that calls are handled in a manner that prioritizes quick and accurate response.

In contrast, other technologies such as access tandems are more related to routing and interconnections among various network switches, but they do not specifically focus on ANI collection and call tracking like CAMA does. ESRK, which pertains to Enhanced Service Routing Keying, is also concerned with routing but does not encompass the complete range of data collection and handling that CAMA provides. ANI itself refers simply to the identification of the calling party but does not describe a technology that collects and processes this information effectively in a centralized manner.
