SUBSCRIBE”请求如何终止SIP对话?

【问题讨论】:

    标签: sip


    【解决方案1】:

    您应该在rfc6665 中找到所有答案。您可以更准确地查看4.2.1.4 节。更新订阅4.4.1节。对话框创建和终止

    引用 rfc 的一些文本:

    这是从订阅者端请求对话结束的方法:

    Clients can cause a subscription to be terminated immediately by
    sending a SUBSCRIBE request with an "Expires" header field set to
    '0'.
    

    以及真正终止对话的最终通知:

    A subscription is destroyed after a notifier sends a NOTIFY request
    with a "Subscription-State" of "terminated", or in certain error
    situations described elsewhere in this document.
