背景
我们的商店由大约 10~12 个 Cisco IP 电话组成，然后连接到各自的工作站。如果我没记错的话，每部电话都连接到商店中唯一的交换机，即 Cisco 2950。此 2950 连接到 Cisco 2811，该 Cisco 2811 保存所有电话的配置。
问题
电话将在一天内持续下降。主电话振铃，如果在 5 次振铃内无人接听，则其他办公电话振铃。当从这些其他电话中接听电话时，电话就会挂断。
如有必要，我可以发布路由器配置，但它很长。如果有人想告诉我什么对配置有帮助，我可以粘贴它。
问题更新
这些是重现问题的步骤。电话A拨打办公室的主线，呼叫被接听并建立。电话 B拨打办公室的主线，振铃 3 次后呼叫被寻线到其他电话。当来自电话 B的呼叫被拿起时，Cisco 7960 电话上的呼叫会掉线，但电话 B 上的呼叫会一直振铃，直到线路再次开始振铃并停止对电话的寻线，此循环直到电话 B挂断为止。
