What information must be recorded about an inmate's phone call according to protocol?

Recording who the inmate called is essential for multiple reasons tied to security, transparency, and proper documentation protocols within the correctional facility. Knowing the recipient of the call allows jail staff to monitor communications effectively, ensuring that no illegal activities are facilitated through phone calls, such as planning escapes, gang activities, or other criminal behaviors.

Moreover, this information is critical for legal purposes and accountability. It allows for compliance with various legal standards and helps to prevent and address any potential breaches of protocol that might arise from interactions between inmates and individuals outside the facility. Additionally, tracking who the inmate communicates with can aid in investigations relating to ongoing criminal cases or complaints regarding inmate behavior.

The other options, while they could also be relevant in maintaining a comprehensive record of inmate communications, do not capture the fundamental aspect of identifying the parties involved in the call, which is a primary concern in correctional management.
