在我看来，你不能这样做。

但是看看DisconnectCause（android.telecom.DisconnectCause），也许这里有一些帮助。

/** Disconnected because of an unknown or unspecified reason. */
public static final int UNKNOWN = 0;
/** Disconnected because there was an error, such as a problem with the network. */
public static final int ERROR = 1;
/** Disconnected because of a local user-initiated action, such as hanging up. */
public static final int LOCAL = 2;
/**
 * Disconnected because of a remote user-initiated action, such as the other party hanging up
 * up.
 */
public static final int REMOTE = 3;
/** Disconnected because it has been canceled. */
public static final int CANCELED = 4;
/** Disconnected because there was no response to an incoming call. */
public static final int MISSED = 5;
/** Disconnected because the user rejected an incoming call. */
public static final int REJECTED = 6;
/** Disconnected because the other party was busy. */
public static final int BUSY = 7;
/**
 * Disconnected because of a restriction on placing the call, such as dialing in airplane
 * mode.
 */
public static final int RESTRICTED = 8;
/** Disconnected for reason not described by other disconnect codes. */
public static final int OTHER = 9;

当然，除了本地或远程挂断之外，还有更多原因。

调查android.telecom.ConnectionService，也许一些hack方式可以实现你的目标。

祝你好运。
