--todo 有空再搞

MicroSIP 向 FreeSWITCH 注冊，transport 設置為 tls

同時?Media Encryption 設置為強制

FreeSWITCH 做一個這樣的路由：

<action application="set" data="rtp_secure_media=optional"/>
<action application="answer" data=""/>
<action application="echo" data=""/>

抓包， MicroSIP 呼叫，Wireshark 打開 pcap

試了試，還沒搞出來，可能是加密套件方面的問題，wireshark 解不出來，還在研究中

但很奇怪，我查過之前的筆記，可以搞出來的，不知道到底怎么回事了

有沒有人總是測試成功？寫篇文章分享下經驗如何？
