VOS3000 NAT保活 Best 配置方法 – 解决语音问题

April 12, 2026

VOS3000 NAT保活Best配置方法 – 解决语音问题 VOS3000 NAT保活功能是解决VoIP环境中常见NAT穿透问题的关键机制，确保位于NAT设备后面的SIP设备能够正常注册和维持呼叫连接。VOS3000 2.1.9.07手册第4.1.2节中记录的NAT保活功能通过定期发送心跳消息来保持NAT映射有效，防止因NAT超时导致的单向音频、注册丢失和呼叫中断等问题。正确配置NAT保活对于任何部署在NAT环境中的VOS3000系统都是至关重要的。网络地址转换(NAT)是VoIP部署中的主要挑战之一，因为SIP协议在设计时并未考虑NAT环境。当SIP设备位于NAT后面时，NAT设备会修改IP地址和端口，导致SIP信令和RTP媒体流出现问题。VOS3000 NAT保活功能通过定期发送UDP心跳消息来保持NAT映射，确保设备可以接收来自软交换的消息。如需NAT保活配置技术支持，请通过WhatsApp联系我们：+8801911119966。 Table of ContentsVOS3000 NAT保活Best配置方法 – 解决语音问题理解NAT对VoIP的影响NAT穿透问题NAT超时机制VOS […]
