非常感谢您对这个问题的帮助。我正在使用 jsSIP 用户代理运行一个非常基本的 JS 脚本，该用户代理使用本地 Asterisk 服务器进行语音呼叫。一切都在专用网络上，我没有从 Asterisk CLI 收到任何警告或错误，但是当我拨打旧版 SIP 电话或测试分机时，尽管有响铃，但任何一侧都没有音频，电话可以接听，而且永远不会掉线。我的 Asterisk 12 是用 SRTP 和 pjproject 编译的。
我在 Asterisk WebRTC Wiki ( https://wiki.asterisk.org/wiki/display/AST/Asterisk+WebRTC+Support ) 上读到：“从 Asterisk 12 开始，您需要安装 pjproject 库，否则您很可能会赢在您的 WebRTC 呼叫中没有音频，也没有任何警告！” 我正确安装了它并选择了它用于 Asterisk 编译，但我想知道我是否做错了，我该如何检查它......

最后，这就是 Asterisk CLI 所说的：当我订阅时：
== WebSocket connection from '192.168.0.4:55061' for protocol 'sip' accepted using version '13'
-- Registered SIP '1001' at 192.168.0.4:55061
当我打电话时：
== Using SIP RTP CoS mark 5
-- Executing [200@myContext:1] Answer("SIP/1001-00000005", "") in new stack
-- Executing [200@myContext:2] Playback("SIP/1001-00000005", "hello-world") in new stack
Sent RTP packet to 192.168.0.4:51805 (via ICE) (type 00, seq 019963, ts 000160, len 000160)

Sent RTP packet to 192.168.0.4:51805 (via ICE) (type 00, seq 019964, ts 000320, len 000160)
我错过了什么明显的东西吗？先谢谢了
