What types of endpoints can be configured in the IPO system?

The choice that includes digital, analog, and IP endpoints correctly identifies the types of endpoints that can be configured in the IPO (IP Office) system. In this system, a wide range of endpoint types are supported to accommodate various telephony needs and infrastructures.

Digital endpoints involve traditional telephone devices that connect to digital lines, providing reliable service within a structured telephony environment. Analog endpoints refer to standard phone lines that utilize analog technology, allowing connections to a variety of phone models. IP endpoints represent modern VoIP (Voice over Internet Protocol) systems that leverage internet connectivity for communication, making them highly versatile and suitable for remote locations or integrated network setups.

The inclusion of all these types highlights the flexibility of the IPO system, allowing users to implement a mixed environment depending on their specific requirements and existing technology. This capability supports the integration of legacy systems while enabling modernization with IP technology, catering to a diverse range of organizational configurations.

In contrast, the other options are too restrictive and do not accurately reflect the comprehensive endpoint support that the IPO system offers.
