这是 Netgear FSM7328S，我们已将 VOIP 电话连接到它。电话会在线几秒钟\几分钟，然后断线，这时，我们需要四处走动并手动重置所有电话，但同样的事情再次发生。此外，交换机上的 GUI 无法正常工作。

答案1
虽然我不是 VoIP 或 Netgear 用户，但这可能是导致掉线的原因：
警察简单 1024 1 符合操作设置 dscp 传输 46 违反行动下降
我猜想您的 VOIPPolicy 未包含 VoIP 电话需要执行的所有操作，并且当它们尝试执行任何操作时都会被丢弃...我会删除违反操作丢弃部分，看看它们之后是否保持在线，然后尝试确定它们在网络方面除了您已在策略中允许它们执行的操作之外还执行了哪些操作。一旦您弄清楚它们在网络上执行的操作，您就可以将该行为纳入策略并重新添加“违反操作丢弃”部分。
