javascript - 尝试使用 jsip 库向 FreeSwitch 发送邀请请求时出现 "488 Incompatible SDP "

Question

邀请请求总是失败，并显示 488 代码。我尝试更改编解码器的优先级，但没有任何帮助。我认为 FreeSwitch 正在等待我发送到的另一个 sdp 参数。但我无法弄清楚。这是来自 jssip 调试器的日志，我刚刚将 ip 地址更改为 x.x.x.x。

UPD。我已经更改了 mux 策略，现在它还发送 rtcp 候选者，但错误仍然相同。我正在发布新日志的另一部分。

UPD 1我更改了多路复用策略，现在它也发送 rtcp 候选项，但仍然不起作用。

Answer 1

答案已发布在评论中，但我在 Google 上找到了此内容，并希望使其更清楚。

这通常是由于 ua.call() 上缺少 STUN 配置造成的。 JsSIP 文档显示了一个示例，但例如使用 google STUN 服务器:

    let options = {
        'mediaConstraints': { 'audio': true, 'video': video },
        'sessionTimersExpires': 120,
        'pcConfig': {
            'iceServers': [
                {
                    'urls': ['stun:stun.l.google.com:19302','stun:stun1.l.google.com:19302']
                }
             ]
         }
    };

    this.currentSession = ua.call('sip:<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="1c696f796e5c7a6e79796f6b75687f74317e7364327f7371" rel="noreferrer noopener nofollow">[email protected]</a>', options)
