这是我第一次使用星号（基本上我什么都不知道，所以请耐心等待）
我在一个具有 512/kbps 互联网连接的虚拟机中运行 Asterisk 11.6，它位于 NAT 后面。
有两个分机 1001 和 1002，这些都是发生在我身上的情况。
数字 1：使用软电话在本地拨打电话。“没问题”。
号码 2：从外部（软电话）呼叫本地工作。“没问题”。
号码 3：本地打外线，直接挂断即可。“问题”。
4号：从外到外的电话，从来不工作。我能听到拨号音，但听筒没有反应。“问题”。
我尝试转发端口 5060 tcp 和 udp 没有任何变化......
我还在某处读到我有 NAT 环回错误，此时它与我无关。
我的问题是我想从外部网络连接这两个扩展......
(1001)网络1--->(服务器)网络2--->(1002)网络3
同样倒退...我错过了什么吗？
这是我的 sip 配置。

这里用户 1001 是“无法访问”的，为什么？我认为这就是我的问题所在。
帮帮我，伙计们...
我也在寻找与 PSTN 和 GSM 连接的方法。
（如果你们来自印度并且可以帮助我，我实际上可以付钱给你，请回答上述问题的解决方案，然后我会联系其他方法）
