Asterisk 只能在 Wifi 网络上听不到声音答案

【问题标题】：Asterisk cannot hear sound on Wifi network onlyAsterisk 只能在 Wifi 网络上听不到声音
【发布时间】：2014-03-28 09:06:55
【问题描述】：

我在 CentOS 6.5 上安装了 Asterisk + FreePBX。

Case 1
Asterisk + FreePBX + CentOS 6.5
Phone A - Android 4G newtork (Linphone, PCMA codec)
Phone B - Android Wifi network (Linphone, PCMA codec)
If I can make a call to Phone B from Phone A, it works and answers the phone. 
However, I can only hear sound from Phone A when I speak on Phone B.

我认为是 NAT 问题，并检查了所有防火墙的 Asterisk。 Wifi网络也没有问题。有没有办法正确更改 NAT 设置？谢谢。

这是我打电话和打电话时的 Asterisk CLI 日志。

Wifi 上的 Android 似乎无法获取正确的地址。它不显示发送语音的特定端口。

【问题讨论】：

asterisk -rvvvvv的输出是什么并尝试sip debug或sip set debug on并配置“nat”和“qualify”（voip-info.org/wiki/view/Asterisk+sip+nat）
我发布了 Asterisk 日志。看起来不错。
您是否已经转发 SIP 端口（UDP 5060、10000-20000）到路由器/防火墙上的星号机器？您需要在 rtp 调试中检查 ip，您应该看到类似：Got RTP packet from <IP>、Sent RTP packet to <IP>。在 sip.conf 的“常规”上下文设置中激活 NAT：nat=yes、externip=<YOUR REAL IP>、localnet=<LOCANET/MASK>。
@pce 是的。我已经打开了这些端口，更改了您提到的设置。它正在LTE网络上工作。但是，它不仅在家里的 Wifi 网络上工作……很奇怪……

【解决方案1】：

这就是我喜欢简单干净的 Asterisk 的原因，你的控制台不会因为一个呼叫而像这样被淹没。 :)

如果您绝对确定编解码器没有问题，则音频 RTP 未到达手机。检查 SIP INVITE 消息的发送位置（假设 1003 是电话不工作）：

> sip show peer 1003

查找编解码器信息。如果它们很好，请查看 NAT。设置

> sip set debug on

或者对于特定的同伴：

> sip set debug on peer 1003

然后检查您的标题，特别是 Contact: 标题，其中显示“嘿，请在此处联系我”。

如果创建了呼叫，这意味着控制信号通过（您可以在任一电话中呼叫和挂断），那么我很确定这是一个编解码器问题。如果控件不是 100% 正常（例如，您在一部手机上挂断而另一部不知道），那么可能是网络问题。

希望对你有帮助！

然后使用 SIP 调试检查他们在哪里发送/期待音频。
好。我检查了它发送语音的联系人数据。它没有特定的端口..现在我需要找出如何去做。也许我需要 stun 服务器才能找到它？ @查理布朗
准确地说，将语音发送到哪里取决于每个呼叫 (INVITE)，在 SDP 描述中它包括端口。但我同意这两个不同的联系人有点奇怪。也许您应该考虑在您的 WiFI 路由器中设置 SIP ALG。对不起，我已经帮不上忙了！
谢谢查理！我发现这是NAT问题。我打开了 Stun 服务器，它现在可以工作了 :)
太棒了！这些绝非易事；）
