FREESWITCH 填坑指南

转接

1.查看网关注册状态 

sofia status

 

2.桥接（未实践） http://wiki.freeswitch.org.cn/wiki/Mod_lua.html#jump10237

freeswitch.bridge

session1 = freeswitch.Session("sofia/internal/1001%192.168.1.1");
session2 = freeswitch.Session("sofia/internal/1002%192.168.1.1");
freeswitch.bridge(session1, session2);

 

http://wiki.freeswitch.org.cn/wiki/Mod_lua.html#jump10237

 

3.diaplan脚本中先呼叫一方，再转接另外一方

 1  prefix = "{ignore_early_media=true}sofia/192.168.150.132/"
 2  file_to_play = "/usr/local/freeswitch/sounds/custom/8000/sound.wav"
 3   
 4  function call_number(number)
 5    dial_string = prefix .. tostring(number);
 6    -- debug("calling " .. dial_string);
 7    session = freeswitch.Session(dial_string);
 8    session:setAutoHangup(false)
 9    session:transfer("5002", "XML", "default")
10    return session:hangupCause()
11  end
12  hangup_cause = call_number("1012")

 

freeswitch下执行lua脚本运行

luarun autodia.lua param1

 

若是经过客户端执行，能够调用fs_cli ，调用完成后退出客户端命令以下：

bin/fs_cli -x "luarun autodia.lua param1"

 

 

 

 

 4.fs_cli链接不上问题

 a.能够看8021端口是否使用，若是是的

 

相关配置文件 conf/autoload_configs/event_socket.conf.xml

 <configuration name="event_socket.conf" description="Socket Client">
   <settings>
     <param name="nat-map" value="false"/>
- <param name="listen-ip" value="::"/>
+ <param name="listen-ip" value="127.0.0.1"/>
     <param name="listen-port" value="8021"/>
     <param name="password" value="ClueCon"/>
- <!--<param name="apply-inbound-acl" value="loopback.auto"/>-->
- <!--<param name="stop-on-bind-error" value="true"/>-->
+ <!--<param name="apply-inbound-acl" value="lan"/>-->
   </settings>
 </configuration>

配置改为以下配置便可

<configuration name="event_socket.conf" description="Socket Client">
  <settings>
    <param name="nat-map" value="false"/>
    <param name="listen-ip" value="127.0.0.1"/>
    <param name="listen-port" value="8021"/>
    <param name="password" value="ClueCon"/>
    <!--<param name="apply-inbound-acl" value="loopback.auto"/>-->
    <!--<param name="stop-on-bind-error" value="true"/>-->
  </settings>
</configuration>

 

 

 

b. ip最好改为本机，否者仍有可能拒绝访问

 

 

5.FREESWITCH转接语音到MRCP Server接收到的音频音质极差问题

　　通常是FREEWTICH与终端的音频编码和与MRCP Server的编码不一致致使（终端音频码率较高），FS进行转码时失真过大，SF转码能力可能有些欠缺。经过修改FREESWITCH 目录下conf/vars.xml 将 global_codec_prefs 配置限制为MRCP Server可以接收的编码便可。

<X-PRE-PROCESS cmd="set" data="global_codec_prefs=PCMU,PCMA"/>

 

 

6.单模块编译安装

当已经安装好freeswitch，须要安装一个未安装的模块步骤

1.进入freeswitch-version源码目录

修改module.conf 启动你的安装的模块如mod_json_cdr

2.进入src/mod目录下，make mod_json_cdr

3.在src/mod目录下 make mod_json_cdr-install  

4.在FREESWITCH控制台 load mod_json_cdr

 

 

 

7.集成mod_unimrcp 并对接unimrcpserver

　a.FREESWITCH源码根路径下，修改modules.conf文件，取消“asr_tts/mod_unimrcp”配置的注释

    b. make mod_unimrcp;make mod_unimrcp-install 集成mod_unimrcp模块

　c.切换到安装目录。新建文件conf/mrcp_profiles/unimrcpserver-mrcp-v2.xml，具体配置以下，注意修改ip和端口

<include>
  <!-- UniMRCP Server MRCPv2 -->
  <!-- 后面咱们使用该配置文件，均使用 name 做为惟一标识，而不是文件名 -->
  <profile name="unimrcpserver-mrcp2" version="2">
    <!-- MRCP 服务器地址 -->
    <param name="server-ip" value="127.0.0.1"/>
    <!-- MRCP SIP 端口号 -->
    <param name="server-port" value="8060"/>
    <!-- <param name="resource-location" value=""/> -->

    <!-- FreeSWITCH IP、端口以及 SIP 传输方式 -->
    <param name="client-ip" value="127.0.0.1" />
    <param name="client-port" value="5069"/>
    <param name="sip-transport" value="udp"/>


    <!-- <param name="speechsynth" value="speechsynthesizer"/> -->
    <!-- <param name="speechrecog" value="speechrecognizer"/> -->
    <!--param name="rtp-ext-ip" value="auto"/-->
    <param name="rtp-ip" value="127.0.0.1"/>
    <param name="rtp-port-min" value="4000"/>
    <param name="rtp-port-max" value="5000"/>
    <param name="codecs" value="PCMU PCMA L16/96/8000"/>

    <!-- Add any default MRCP params for SPEAK requests here -->
    <synthparams>
    </synthparams>

    <!-- Add any default MRCP params for RECOGNIZE requests here -->
    <recogparams>
      <!--param name="start-input-timers" value="false"/-->
    </recogparams>
  </profile>
</include>

 

　d.conf/autoload_configs/unimrcp.conf.xml修改配置，将mrcp对接server选择为上面配置的server，使用profile name熟悉值

    <!-- UniMRCP profile to use for TTS -->
    <param name="default-tts-profile" value="unimrcpserver-mrcp2"/>
    <!-- UniMRCP profile to use for ASR -->
    <param name="default-asr-profile" value="unimrcpserver-mrcp2"/>

 

　e. conf/autoload_configs/modules.conf.xml增长以下配置项，让fs启动时自动加载该模块

<load module="mod_unimrcp" />

 

8.sip、rtp对接配置，修改conf/sip_profiles/external.xml。若是走的是代理等网络，须要视状况将auto-nat改成外部ip（若是本机即有外部ip或者对端支持nat，则可能不须要配置）。

    <param name="ext-rtp-ip" value="auto-nat"/>
    <param name="ext-sip-ip" value="auto-nat"/>

 

9.对接mod_format_cdr

　　a.编译安装模块，同上

　　b.启用模块，同上

　　c.配置，修改 conf/autoload_configs/format_cdr.conf.xml，其中几个配置项须要修改

　　

<!-- 配置格式 -- >
<param name="format" value="json"/>
<!-- 回调监听地址 -- >
<param name="url" value="http://sms-agent-idc.vpc.tencentyun.com/aicsCall/cdr/callRecord.do"/>
<!-- key格式配置，appljson能够传递jsonbody，可是header处理彷佛有问题，只能是application/x-www-form-urlencoded，所以使用默认配置 -- >
<param name="encode" value="true"/>
<!-- val是否进行URL编码 -- >
<param name="encode-values" value="false"/>

 

10.禁用ipv6，若是系统不支持，可能会刷以下错误信息，禁用便可

2018-09-14 17:55:34.161271 [ERR] sofia.c:3146 Error Creating SIP UA for profile: external-ipv6 (sip:mod_sofia@[::1]:5080;transport=udp,tcp) ATTEMPT 2 (RETRY IN 5 SEC)

The likely causes for this are:
1) Another application is already listening on the specified address.
2) The IP the profile is attempting to bind to is not local to this system.
