发起音视频呼叫
if (isVideo) {
createVideoViews();
}
NSString *dialablePhone = ContactsGetPhoneWithCountryCode(phone);
ZCHAR *uri = Mtc_UriFormatX((ZCHAR *)[dialablePhone UTF8String], ZFALSE);

Zmf_AudioOutputStart(ZmfAudioDeviceVoice, 0, 0);
注：isVideo 判断是否是视频呼叫i。
呼叫成功后会依次触发以下回调：
static ZVOID MtcCallCbOutgoing(ZULONG dwSessId) {
//通话记录插入数据库
//设置扬声器方式
MtcUtilSetSpeaker(mHasVideo);
if (mHasVideo) {
//设置长度、宽度、帧速率
Zmf_VideoCaptureStart(ZmfVideoCaptureFront, 1280, 720, 30);
//若为视频呼叫，则开启本地视频预览
Zmf_VideoRenderAdd((__bridge void *)_preview, ZmfVideoCaptureFront, 0, ZmfRenderFullScreen);
//将这路视频通话绑定到设备
Mtc_SessCameraAttach(dwSessId, ZmfVideoCaptureFront);
}
}
static ZVOID MtcCallCbAlerted(ZULONG dwSessId, ZULONG dwAlertType){
//开始响铃，界面显示振铃中
}
音视频呼叫来电
当接到电话时，会触发以下回调：
static ZVOID MtcCallCbIncoming(ZULONG dwSessId) {
// 获取来电号码，插入数据库
ZCHAR *pcParptId = ZNULL;
ZBOOL bHasVideo;
Mtc_SessGetPeerId(dwSessId, ZNULL, &pcParptId);
NSString *peerNumber = [NSString stringWithUTF8String:Mtc_UriGetUserPart(pcParptId)];
/* not support multi peer to peer call, if incoming while calling, return */
if ([self isCalling] || [self isTalking]) {
Mtc_SessTerm(dwSessId, EN_MTC_CALL_TERM_REASON_BUSY);
return;
}
BOOL mHasVideo = Mtc_SessPeerOfferVideo(dwSessId);
//界面刷新显示来电，并开始响铃，若为视频通话，则开启本地预览
if (mHasVideo) {
createVideoViews();
//设置长度、宽度、帧速率
Zmf_VideoCaptureStart(ZmfVideoCaptureFront, 1280, 720, 30);
//若为视频呼叫，则开启本地视频预览
Zmf_VideoRenderAdd((__bridge void *)_preview, ZmfVideoCaptureFront, 0, ZmfRenderFullScreen);
//将这路视频通话绑定到设备
Mtc_SessCameraAttach(dwSessId, ZmfVideoCaptureFront);
}
}
接听音视频呼叫
Mtc_SessAnswer(dwSessId, 0, ZTRUE, isVideo); Zmf_AudioInputStart(ZmfAudioDeviceVoice, 0, 0, ZmfAudioDeviceVoice ? ZmfAecOn : ZmfAecOff, ZmfAgcOn); Zmf_AudioOutputStart(ZmfAudioDeviceVoice, 0, 0);
对方触发以下回调
static ZVOID MtcCallCbTalking(ZULONG dwSessId) {
//callId是数据库自增Id
NSInteger callId = [[MtcCallManager sharedInstance] getCallIdWithConfId:dwSessId];
Mvc_ResumeAllStrm();
Mvd_ResumeAllStrm();
//根据CallId，更新数据库状态并通知界面刷新，若为视频通话，则开启本端以及对端视频
if (Mtc_SessHasVideo(dwSessId)) {
//设置扬声器
MtcUtilSetSpeaker(!MtcUtilIsHeadSet());
Mvd_ResumeAllStrm();
Mtc_SessVideoStart(dwSessId);
//开始远端图像预览
Zmf_VideoRenderAdd((__bridge void *)_remote, Mtc_SessGetName(dwSessId), 0, ZmfRenderFullScreen);
}
}
取消音视频呼叫
//主动挂断 //第二个参数，主动挂断的状态码只能选择以下三种之一： //EN_MTC_CALL_TERM_STATUS_NORMAL 正常挂断 //EN_MTC_CALL_TERM_STATUS_BUSY 正忙 //EN_MTC_CALL_TERM_STATUS_DECLINE 拒接 Mtc_SessTerm(dwSessId, MTC_CALL_TERM_NORMAL);
对方收到回调：

// dwStatCode为结束通话的状态码，根据 dwStatCode 判断终止原因，更新数据库状态
// MTC_CALL_TERM_BYE /**< @brief Terminated by bye. */
