我有 2 个 UAC 连接到 FreeSWITCH。第 1 方调用第 2 方。第 2 方拒绝调用(使用“拒绝”或“此处忙”)。但 FreeSWITCH 不会向第一方发送“拒绝”。相反，它会通过 SDP 发送 OK，这实际上会发起调用。
如何解决这个问题？
FreeSWITCH 到第 2 方:

最佳答案
我的猜测是您的 FreeSwitch 拨号计划正在故障转移到录制的故障消息、语音邮件系统或其他东西。对第一方的 200 响应是这样他们可以收听预先录制的错误消息。 FreeSwitch 控制台应该为您提供更多有关其正在执行的操作的提示。
关于voip - 问题: FreeSWITCH does not resend 'Decline' or 'Busy here' ，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/6249973/
