摘要： A method for reducing Internet bandwidth used for data transfer between an originating modem and an answering modem over a VoIP connection is provided. Idle data received from the originating modem is detected by an Internet node. The Internet node does not forward the detected received idle data over the VoIP connection. To keep the modem connection between the originating modem and the answering modem alive, the Internet node regenerates idle data and transmits the regenerated idle data to the answering modem upon detecting no data received for forwarding to the answering modem.
摘要翻译：提供了一种通过VoIP连接减少用于始发调制解调器和应答调制解调器之间的数据传输的因特网带宽的方法。由起始调制解调器接收的空闲数据由互联网节点检测。因特网节点不通过VoIP连接转发检测到的接收到的空闲数据。为了保持始发调制解调器和应答调制解调器之间的调制解调器连接，互联网节点重新生成空闲数据，并且在检测到没有收到的数据转发到应答调制解调器时，将再生的空闲数据发送到应答调制解调器。

摘要： The type of audio stored in the payload of a data packet transmitted over a data network is identified as speech audio or non-speech audio through the use of a non-speech identifier included in a header in the data packet. Upon detection of data packet containing non-speech audio, the receiver of the data packet may modify jitter buffer latency while the non-speech audio is being received. Modifying the jitter buffer latency while non-speech audio is being received minimizes the loss of spoken words during jitter buffer latency modification.
摘要翻译：存储在通过数据网络发送的数据分组的有效载荷中的音频的类型通过使用包含在数据分组中的报头中的非语音标识符来识别为语音音频或非语音音频。当检测到包含非语音音频的数据分组时，数据分组的接收机可以在接收到非语音音频时修改抖动缓冲器等待时间。正在接收非语音音频时修改抖动缓冲区延迟会最大限度地减少抖动缓冲区延迟修改期间口令字的丢失。
