更新時(shí)間:2019-11-20
用戶可以將正在進(jìn)行的視頻通話保持,待需要的時(shí)候再恢復(fù)通話,能減少撥號(hào)次數(shù),使用更方便。
視頻通話已建立,主被叫正在通話中。
保持通話
通話中,主被叫雙方均可以發(fā)起保持通話操作。
視頻通話保持,需先移除視頻,再保持音頻通話;恢復(fù)通話,需先恢復(fù)音頻通話,再打開(kāi)視頻。
當(dāng)前服務(wù)器暫不支持視頻通話保持,需要先移除視頻窗口,轉(zhuǎn)換為語(yǔ)音通話后再保持通話。
-(BOOL)holdCallWithCallId:(unsigned int)callId { TSDK_RESULT ret = tsdk_hold_call(callId); DDLogInfo(@"Call_Log: tsdk_hold_call = %@",(TSDK_SUCCESS == ret)?@"YES":@"NO"); return ret == TSDK_SUCCESS ? YES : NO; }

恢復(fù)通話
保持通話發(fā)起方才可進(jìn)行恢復(fù)通話操作。
-(BOOL)unHoldCallWithCallId:(unsigned int)callId { TSDK_RESULT ret = tsdk_unhold_call(callId); return ret == TSDK_SUCCESS ? YES : NO; }
恢復(fù)通話可能由于網(wǎng)絡(luò)側(cè)極低概率的沖突或異常,導(dǎo)致用戶恢復(fù)通話失敗,此時(shí)SDK向UI上報(bào)恢復(fù)通話失敗事件TSDK_E_CALL_EVT_UNHOLD_FAILED,并自動(dòng)掛斷通話。

因通話雙方均可以在本端處于通話態(tài)發(fā)起保持操作,即通話可能會(huì)處于雙向保持態(tài),在任一保持方發(fā)起恢復(fù)通話時(shí),僅能恢復(fù)本端通話狀態(tài),不會(huì)恢復(fù)對(duì)端的通話狀態(tài);視頻通話雙向保持中任一方先恢復(fù)通話,不會(huì)自動(dòng)打開(kāi)視頻。
