【问题描述】：
我已删除我之前的问题并发布此更新：
我的 SIP UAC 出现问题，一旦我收到来自 B2BUA 的呼叫者和被呼叫者的振铃，并且呼叫者在呼叫响铃时挂断了呼叫（我发送取消请求并收到“请求终止" 在呼叫方），被呼叫方不会收到呼叫已被呼叫方终止的任何通知。
但是当被呼叫者拒绝呼叫时，呼叫者会在这里忙。
这是被调用者方面：

我必须在被调用者端拒绝，因为如果我不响应请求，被调用者帐户会陷入循环，然后客户端永远返回忙碌状态，并且请求不会到达该客户端，或者至少直到该帐户已被删除。
还有一件事，B2BUA 不会向拒绝响应发送任何内容，我不应该从服务器收到 ACK 吗？
这是来电者方面：

弗兰克，我试着关注你的细节，也许我错过了什么，因为对方仍然没有收到提前挂断的通知。
知道为什么吗？
提前致谢，
亚当。
