尝试使用 jsip 库向 FreeSwitch 发送邀请请求时出现“ 488 不兼容的 SDP ”

Question

邀请请求始终失败并显示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xxxx。

Answer 1

答案已发布在评论中，但我在谷歌上找到了这个并想让它更清楚。

这通常是由于ua.call(). 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:user@freeswitch-box.com', options)

JsSIP 的文档：https ://jssip.net/documentation/3.4.x/api/ua/#method_call
