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 end12 hangup_cause = call_number("1012")
freeswitch下执行lua脚本运行
luarun autodia.lua param1
如果通过客户端执行，可以调用fs_cli ，调用完成后退出客户端命令如下：
bin/fs_cli -x "luarun autodia.lua param1"
4.fs_cli连接不上问题
a.可以看8021端口是否使用，如果是的
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>配置改成如下配置即可
b. ip最好改成本机，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
一般是FREEWTICH与终端的音频编码和与MRCP Server的编码不一致导致（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。通过修改FREESWITCH 目录下conf/vars.xml 将 global_codec_prefs 配置限制为MRCP Server能够接收的编码即可。
6.单模块编译安装
当已经安装好freeswitch，需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，具体配置如下，注意修改ip和端口
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
e. conf/autoload_configs/modules.conf.xml增加如下配置项，让fs启动时自动加载该模块
8.sip、rtp对接配置，修改conf/sip_profiles/external.xml。如果走的是代理等网络，需要视情况将auto-nat改为外部ip（如果本机即有外部ip或者对端支持nat，则可能不需要配置）。
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，其中几个配置项需要修改
10.禁用ipv6，如果系统不支持，可能会刷如下错误信息，禁用即可

禁用方式：
mv conf/sip_profiles/internal-ipv6.xml conf/sip_profiles/internal-ipv6.xml.bkmv conf/sip_profiles/external-ipv6.xml conf/sip_profiles/external-ipv6.xml.bk
