UPD 1我已经更改了多路复用策略，现在它也在发送 rtcp 候选项，但仍然不起作用。
答案发布在评论中，但我在谷歌上找到了这个，想让它更清楚。
这通常是由于ua.call()上缺少 STUN 配置引起的。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:user@freeswitch-box.com', options)
