+## cl.telephony.1 call模块接口变更
+
+VoNRState接口枚举值变更，VONR_STATE_ON 枚举值从0变为1，VONR_STATE_OFF枚举值定义为0，与布尔值保持一致，方便用户理解
+
+**变更影响**
+
+setVoNState接口中参数VoNRState枚举值变更，须用户使用最新枚举值调用接口。接口功能不变。
+
+**关键的接口/组件变更**
+
+修改前的接口原型：
+
+```js
+function setVoNRState(slotId: number, state: VoNRState, callback: AsyncCallback<void>): void;
+
+/**
+ * @systemapi Hide this for inner system use.
+ * @since 10
+ */
+export enum VoNRState {
+    /** Indicates the VoNR switch is on */
+    VONR_STATE_ON = 0,
+}
+```
+
+修改后的接口原型：
+
+```js
+function setVoNRState(slotId: number, state: VoNRState, callback: AsyncCallback<void>): void;
+
+/**
+ * Indicates the VoNR state.
+ *
+ * @enum { number }
+ * @syscap SystemCapability.Telephony.CallManager
+ * @systemapi Hide this for inner system use.
+ * @since 10
+ */
+export enum VoNRState {
+    /**
+     * Indicates the VoNR switch is off.
+     *
+     * @syscap SystemCapability.Telephony.CallManager
+     * @systemapi Hide this for inner system use.
+     * @since 10
+     */
+    VONR_STATE_OFF = 0,
+
+    /**
+     * Indicates the VoNR switch is on.
+     *
+     * @syscap SystemCapability.Telephony.CallManager
+     * @systemapi Hide this for inner system use.
+     * @since 10
+     */
+    VONR_STATE_ON = 1,
+}
+```
+
+
+**适配指导**
+
+使用变更后的接口，示例代码如下：
+
+```js
+call.setVoNRState( 0, VONR_STATE_ON, (err) => {
+    console.log(`callback: err->${JSON.stringify(err)}`);
+});
+call.setVoNRState( 0, VONR_STATE_OFF, (err) => {
+    console.log(`callback: err->${JSON.stringify(err)}`);
+});
+```
