Question

有人可以告诉我为什么会这样吗？

iOS10，iPhone5s，VOIP Siphon pjsip2.5.5。

这些问题并非每次都出现，有时候您想拨打电话或接听电话（添加于：20161226）。

Answer 1

第1步：首先在支持文件文件夹中的xcode项目中打开 info.plist 文件，然后点击中的＆＃34; +＆＃34; 信息属性列表。

步骤2：在列表中选择并添加隐私 - 麦克风使用说明。

步骤3：在隐私权 - 麦克风使用说明中添加值麦克风。

现在编译并运行您的项目。

Answer 2

我的问题是，当我在来电时播放声音时，我将AudioSession caterogry Playback设置为：

try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)

我将其更改为播放和录制：

try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayAndRecord)

然后它起作用了。因此，如果您在代码中的某个位置将音频会话设置为播放，请将其更改为播放和录制。

@Altanai

func setAudioSessionActive(active: Bool) -> Bool{
    let sessionInterface = AVAudioSession.sharedInstance()
    do{
        try sessionInterface.setActive(active)

        if(active){
            if(sessionInterface.category != AVAudioSessionCategoryPlayAndRecord){
                try sessionInterface.setCategory(AVAudioSessionCategoryPlayAndRecord)
            }
            if(sessionInterface.mode != AVAudioSessionModeVoiceChat){
                try sessionInterface.setMode(AVAudioSessionModeVoiceChat)
            }
        }
        return true
    }
    catch let error{
        return false
    }
}

func configureAudioSession(){
    let sessionInterface = AVAudioSession.sharedInstance()

    do{
        if(sessionInterface.responds(to: #selector(AVAudioSession.setCategory(_:with:)))){
            try sessionInterface.setCategory(AVAudioSessionCategoryPlayAndRecord, with: AVAudioSessionCategoryOptions.allowBluetooth)
        }
        else{
            try sessionInterface.setCategory(AVAudioSessionCategoryPlayAndRecord)
        }
        try sessionInterface.setMode(AVAudioSessionModeVoiceChat)

    }
    catch let error{
        NSLog("SipManager - configureAudioSession error: \(error)")
    }
}

最后，我用IOS的CallKit解决了这个问题，看看这个网站：https://trac.pjsip.org/repos/ticket/1941

详细信息：CallKit框架允许应用使用本机手机用户界面接听来电并拨打电话。为了实现这一点，CallKit要求呼叫音频仅在音频会话被激活时启动，因此建议在使用PJSIP时，仅在必要时打开声音设备。它可以通过以下方式完成：

在没有声音设备的情况下启动PJSIP（通过在启动后调用pjsua_set_no_snd_dev（））。未使用时关闭声音设备，也使用相同的API（pjsua_set_no_snd_dev（））。音频会话激活后，使用API pjsua_set_snd_dev（）打开声音设备。下面是一个关于如何将CallKit与PJSIP集成的示例，其代理功能取自Apple提供的Speakerbox示例应用程序。

拨打电话：

func provider(_ provider: CXProvider, perform action: CXStartCallAction) {
        /* 1. We must not start call audio here, and can only do so
         *    once the audio session has been activated by the system
         *    after having its priority elevated. So, make sure that the sound
         *    device is closed at this point.
         */

        /* 2. Provide your own implementation to configure
         *    the audio session here.
         */
        configureAudioSession()

        /* 3. Make call with pjsua_call_make_call().
         *    Then use pjsua's on_call_state() callback to report significant
         *    events in the call's lifecycle, by calling iOS API
         *    CXProvider.reportOutgoingCall(with: startedConnectingAt:) and
         *    CXProvider.reportOutgoingCall(with: ConnectedAt:)
         */

        /* 4. If step (3) above returns PJ_SUCCESS, call action.fulfill(),
         *    otherwise call action.fail().
         */
    }

处理来电：

 func provider(_ provider: CXProvider, perform action: CXAnswerCallAction) {
        /* 1. We must not start call audio here, and can only do so
         *    once the audio session has been activated by the system
         *    after having its priority elevated. So, make sure that the sound
         *    device is closed at this point.
         */

        /* 2. Provide your own implementation to configure
         *    the audio session here.
         */
        configureAudioSession()

        /* 3. Answer the call with pjsua_call_answer().
         */

        /* 4. If step (3) above returns PJ_SUCCESS, call action.fulfill(),
         *    otherwise call action.fail().
         */
    }

启动声音设备：

func provider(_ provider: CXProvider, didActivate audioSession: AVAudioSession) {
    /* Start call audio media, now that the audio session has been
     * activated after having its priority boosted.
     *
     * Call pjsua API pjsua_set_snd_dev() here.
     */
}
