TCP is worse for VoIP (interactive media in general) because of the extra traffic, delay and jitter it introduces. Voice codecs have enough Forward Error Correction and interpolation capability to tolerate a lost packet here and there. Increased transport delay plus buffers needed for jitter can increase lag to intolerable levels in a conversation.
For better voice quality use a "HD" codec instead.

它是全双工的。
TCP 对于 VoIP（一般交互式媒体）来说更糟糕，因为它会带来额外的流量、延迟和抖动。语音编解码器具有足够的前向纠错和插值能力，可以容忍各处丢失的数据包。增加的传输延迟加上抖动所需的缓冲区可能会将会话中的延迟增加到无法容忍的水平。
为了获得更好的语音质量，请改用“HD”编解码器。
It's full duplex.
