FREESWITCH 填坑指南

1.查看網關注冊狀態(tài)

sofia status

2.橋接（未實踐） 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腳本中先呼叫一方，再轉接另一方

prefix = "{ignore_early_media=true}sofia/192.168.150.132/"
 file_to_play = "/usr/local/freeswitch/sounds/custom/8000/sound.wav"
  
 function call_number(number)
   dial_string = prefix .. tostring(number);
   -- debug("calling " .. dial_string);
   session = freeswitch.Session(dial_string);
   session:setAutoHangup(false)
   session:transfer("5002", "XML", "default")
   return session:hangupCause()
 end
 hangup_cause = call_number("1012")

freeswitch下執(zhí)行l(wèi)ua腳本運行

如果通過客戶端執(zhí)行缀拭，可以調用fs_cli 粪般，調用完成后退出客戶端命令如下：

bin/fs_cli -x "luarun autodia.lua param1

4.fs_cli連接不上問題

a.可以看8021端口是否使用，如果是的

相關配置文件 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>

配置改成如下配置即可

按 Ctrl+C 復制代碼

b. ip最好改成本機，否者仍有可能拒絕訪問

5.FREESWITCH轉接語音到MRCP Server接收到的音頻音質極差問題

一般是FREEWTICH與終端的音頻編碼和與MRCP Server的編碼不一致導致（終端音頻碼率較高）箩艺，FS進行轉碼時失真過大眯分，SF轉碼能力可能有些欠缺。通過修改FREESWITCH 目錄下conf/vars.xml 將 global_codec_prefs 配置限制為MRCP Server能夠接收的編碼即可缚甩。

6.單模塊編譯安裝

當已經安裝好freeswitch谱净，需要安裝一個未安裝的模塊步驟

1.進入freeswitch-version源碼目錄

修改module.conf 啟動你的安裝的模塊如mod_json_cdr

2.進入src/mod目錄下，make mod_json_cdr

3.在src/mod目錄下 make mod_json_cdr-install

4.在FREESWITCH控制臺 load mod_json_cdr

7.集成mod_unimrcp 并對接unimrcpserver

a.FREESWITCH源碼根路徑下擅威，修改modules.conf文件壕探，取消“asr_tts/mod_unimrcp”配置的注釋

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

c.切換到安裝目錄。新建文件conf/mrcp_profiles/unimrcpserver-mrcp-v2.xml郊丛，具體配置如下李请，注意修改ip和端口

<include>
  <!-- UniMRCP Server MRCPv2 -->
  <!-- 后面我們使用該配置文件，均使用 name 作為唯一標識厉熟，而不是文件名 -->
  <profile name="unimrcpserver-mrcp2" version="2">
    <!-- MRCP 服務器地址 -->
    <param name="server-ip" value="127.0.0.1"/>
    <!-- MRCP SIP 端口號 -->
    <param name="server-port" value="8060"/>
    <!-- <param name="resource-location" value=""/> -->

    <!-- FreeSWITCH IP导盅、端口以及 SIP 傳輸方式 -->
    <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></pre>

d.conf/autoload_configs/unimrcp.conf.xml修改配置，將mrcp對接server選擇為上面配置的server揍瑟，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"/></pre>

e. conf/autoload_configs/modules.conf.xml增加如下配置項白翻，讓fs啟動時自動加載該模塊

<load module="mod_unimrcp" />

8.sip、rtp對接配置绢片，修改conf/sip_profiles/external.xml滤馍。如果走的是代理等網絡，需要視情況將auto-nat改為外部ip（如果本機即有外部ip或者對端支持nat杉畜，則可能不需要配置）纪蜒。

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

9.對接mod_format_cdr

a.編譯安裝模塊，同上

b.啟用模塊此叠，同上

c.配置纯续，修改 conf/autoload_configs/format_cdr.conf.xml随珠，其中幾個配置項需要修改

<!-- 配置格式 -- >
<param name="format" value="json"/>
<!-- 回調監(jiān)聽地址 -- >
<param name="url" value="http://sms-agent-idc.vpc.tencentyun.com/aicsCall/cdr/callRecord.do"/>
<!-- key格式配置，appljson可以傳遞jsonbody猬错，但是header處理似乎有問題窗看，只能是application/x-www-form-urlencoded，因此使用默認配置 -- >
<param name="encode" value="true"/>
<!-- val是否進行URL編碼 -- >
<param name="encode-values" value="false"/>

10.禁用ipv6倦炒，如果系統(tǒng)不支持显沈，可能會刷如下錯誤信息，禁用即可
