我正在尝试设置运行freeSWITCH的Docker容器,以便我可以在Debian服务器上部署它。
为了开发,我使用在boot2docker中运行freeSWITCH容器的Mac。
我需要容器才能在这两种环境中工作。
我设法通过软电话连接到FS服务器并拨打电话但是在32秒后,呼叫会中断。
freeswitch@internal> version
FreeSWITCH Version 1.4.15-1~64bit (-1 64bit)
这是FS发送的SIP 200 OK数据包,并期望得到答案:

我猜FS从未收到软电话的答案,因为各种NAT层并且掉线,假设它没有连接。
192.168.1.141是我在局域网上的Mac的IP地址(如200 OK数据包的VIA所示)
192.168.59.103是boot2docker VM
192.168.59.3是我在boot2docker虚拟网络上的Mac
172.17.0.xxx是Docker网络上FS服务器的IP地址(此IP会发生变化,具体取决于以前运行的容器数量)
这就是我在sip_profiles / internal.xml上的内容
<param name="rtp-ip" value="$${local_ip_v4}"/>
<!-- ip address to bind to, DO NOT USE HOSTNAMES ONLY IP ADDRESSES -->
<param name="sip-ip" value="$${local_ip_v4}"/>
<param name="hold-music" value="$${hold_music}"/>
<param name="apply-nat-acl" value="nat.auto"/>
<!-- Docker NAT magic -->
<param name="ext-sip-ip" value="$${external_sip_ip}"/>
<param name="ext-rtp-ip" value="$${external_rtp_ip}"/>
在我的vars.xml中
<X-PRE-PROCESS cmd="set" data="external_rtp_ip=192.168.59.103"/>
<X-PRE-PROCESS cmd="set" data="external_sip_ip=192.168.59.103"/>
来自fs_cli:
freeswitch@internal> eval ${external_rtp_ip}
192.168.59.103
freeswitch@internal> eval ${external_sip_ip}
192.168.59.103
freeswitch@internal> eval ${ext-rtp-ip}
-ERR no reply
freeswitch@internal> eval ${ext-sip-ip}
-ERR no reply
我为RTP流量设置了端口16384到16484 UDP,5060,5070,5080 UDP&amp;用于SIP的TCP,包括FS和容器中的。
回声测试显示音频双向流动。
知道发生了什么以及如何解决?

我的FreeSwitch安装遇到了类似的问题,我通过配置交换机不断ping注册的软电话来解决这个问题,以保持NAT防火墙通道畅通。以下是为我做的设置:
<param name="nat-options-ping" value="true"/>
<param name="all-reg-options-ping" value="true"/>
<!-- One successful options ping is enough to verify that a phone is reachable -->
<param name="sip-user-ping-min" value="1"/>
<!-- Three pings need to be lost to consider the phone disconnected -->
<param name="sip-user-ping-max" value="4"/>
<param name="unregister-on-options-fail" value="true"/>
<!-- Freeswitch is coded to send
pings at variable intervals with the mean value determined by the
variable below and a normal distribution with a deviation of half the
interval value. -->
<param name="ping-mean-interval" value="15"/>
他们转到sip_profiles / internal.xml。

好的,这是更新。
事实证明问题是因为FS无法正确检测到其IP并且它发回的数据包包含在错误的IP中。
我想出了这个脚本作为我的容器启动序列的一部分: https://github.com/Coaxial/mushimushi/blob/a29ae537314e89bc7f9808c2bd7fdb4917eafa04/lib/freeswitch_conf/start.sh#L7-L21
然后我将生成的XML文件包含在常规配置中:https://github.com/Coaxial/mushimushi/blob/a29ae537314e89bc7f9808c2bd7fdb4917eafa04/lib/freeswitch_conf/freeswitch.xml#L3
这样我可以引用变量来配置相关的Sofia配置文件:https://github.com/Coaxial/mushimushi/blob/a29ae537314e89bc7f9808c2bd7fdb4917eafa04/lib/freeswitch_conf/autoload_configs/sofia.conf.xml#L29-L32
这在boot2docker中运行时有效,但在&#34; vanilla&#34;码头工人。
