A call control feature exists on the iOS platform which restricts the ability of the recipient of a phone call to terminate the connection. The initiator of the call retains exclusive control over the disconnection process. This means the person receiving the call cannot hang up; only the caller can end the call.
The primary benefit of such a configuration is maintaining control and ensuring the intended message is delivered fully. In customer service or technical support scenarios, for instance, it could be employed to prevent premature call termination before complete resolution or information dissemination. While this feature isn’t a standard iOS setting available to the average user, it could be implemented within custom applications or specialized mobile device management (MDM) configurations. The historical use cases would typically center around controlled communication environments.
