如何在码头和外界的sipster / pjsip之间启用声音连接？ [英] How to enable sound connection between sipster / pjsip in docker and outside world?

问题描述

使用sipster / pjsip成功安装我想要遵循基本的sipster示例并记录声音从sip连接到该sip服务器。现在如果我在一个本地的arch linux机器上运行，声音将被完全记录下来，但是如果我在Docker机器上执行相同的操作，那么我从

$ pre ＃code> docker run -p 5060：5060 / udp -it myContainer

SIP连接工作，但没有录音。

朋友告诉我，SIP使用RTP进行声音传输，并且该协议将UDP端口从16384绑定到32767。

现在如果我做

  docker run -p 5060：5060 / udp  - p 16384-32767：16384-32767 / udp -it myContainer 
  

这需要年龄并最终崩溃。 / p>

有没有办法缩小sipster或pjsip中的RTP端口范围？我甚至在正确的轨道上，或者可能问题与没有声音设备的码头连接？

解决方案

Docker是不能一次映射很多端口。在我的情况下，我创建了一个rtpproxy映像，然后我创建了几个docker容器实例，每个容器映射1000个1000个端口。

我正在和很多人谈论它和每个人都说我很疯狂，为什么我需要10k端口映射..那么我必须解释VoIP如何工作...

With sipster/pjsip sucessfully installed I would like to follow through the basic sipster example and record the sound from a sip connection to that sip server. Now if I run this on a local arch linux machine the sound gets recorded fully, but if I do the same on a docker machine, that I start with

docker run -p 5060:5060/udp -it myContainer

the SIP connection works, but there is no sound recorded.

A friend told me that SIP uses RTP for sound transport and that this protocol binds UDP ports from 16384 to 32767.

Now if I do

docker run -p 5060:5060/udp -p 16384-32767:16384-32767/udp -it myContainer

this takes ages and crashes eventually.

Is there a way to narrow down the RTP port range in sipster or pjsip? And am I even on the right track or might the issue be connected to the docker not having a sound device?

解决方案

Docker is not able to map a lot of ports at once. In my case I created a rtpproxy image and then I create several docker containers instances mapping 1000-by-1000 ports per container.

I am talking to a lot of guys about it and everybody says I am crazy and why I need 10k ports mapped .. then I have to explain how VoIP works ...
