我们的 Cisco CME 在办公室遇到了问题。这是情况。
电话 A（外线）拨入主线，大约三声振铃后，呼叫被寻线至其他四部电话。电话 X 接听电话 A 的来电，可以开始通信，没有问题。我们将其称为“原始呼叫”

然后电话 B（外线）拨入主线，再响铃三声后，呼叫又转至其他四部电话。电话 Y 尝试接听来自电话 B 的来电，但电话 Y 上的呼叫掉线，而电话 B 上的呼叫继续振铃。来自电话 B 的电话实际上处于不确定状态，只要原始呼叫仍在会话中，就永远无法建立到电话 B 的连接，电话 B 必须终止他们的呼叫。

为什么当电话 Y 或任何与此相关的电话尝试接听电话 B 的电话时，电话永远无法接通？

请参阅下面的路由器配置以供参考。我以为这可能与 ，huntstop channel但那是错误的。也许这与呼叫代答配置有关，但我不太确定。

一个debug voip ccapi inout日志已被放置在引擎收录。
此外，如果从未接听来自电话 B 的呼叫，该呼叫将继续在电话 B 上振铃和振铃，而在所有 7960 电话上响铃约 8 次后，呼叫将被寻线停止。如果电话从未被接听，则呼叫被断开（原因代码 16）并且呼叫从未被转发到语音信箱noan。
