FreeSWITCH部署与功能配置
提示：扫一扫查出行【扫一扫了解最新限行尾号】
复制提示
一.FreeSWITCH服务部署
1.wget http://www.freeswitch.org.cn/Makefile && make install
2.cd freeswitch
3.运行./bootstrap.sh(作用：初始化环境)
4.执行./configure(主要的作用是对即将安装的软件进行配置，检查当前的环境是否满足要安装软件的依赖关系，但并不是所有的tar包都是源代码的包)
5.make install
6.修改配置文件/usr/local/freeswitch/conf/vars.xml中的默认密码
<X-PRE-PROCESS cmd="set" data="default_password=1234"/>
7./usr/local/freeswitch/bin
执行 ./freeswitch -nc -nonat启动
执行 ./freeswitch -stop关闭
二.用户批量配置
/usr/local/freeswitch/conf/directory/default/2000.xml
1 <include>
2 <user id="2000" number-alias="root">
3 <params>
4 <param name="password" value="123456"/>
5 <param name="reverse-auth-user" value="2000"/>
6 <param name="reverse-auth-pass" value="123456"/>
7 <param name="vm-password" value="c99ecff92015"/>
8 <param name="vm-enabled" value="true"/>
9 <param name="directory-exten-visible" value="true"/>
10 <param name="dial-string" value="{sip_invite_domain=${domain_name},leg_timeout=30,presence_id=${dialed_user}@${dialed_domain}}${sofia_contact(${dialed_user}@${dialed_domain})}"/>
11 </params>
12 <variables>
13 <variable name="domain_name" value="xxx.xxx.xxx.xxx"/>
14 <variable name="toll_allow" value=""/>
15 <variable name="user_context" value="default"/>
16 <variable name="directory-visible" value="true"/>
17 <variable name="limit_max" value="5"/>
18 <variable name="sip-force-contact" value="NDLB-connectile-dysfunction-2.0"/>
19 <variable name="sip-force-expires" value="180"/>
20 </variables>
21 </user>
22 </include>
批量生成用户脚本：
1 #!/bin/bash
2 for ((a=20000;a<=20010;a++)) ;
3 do
4 i=$(echo $a)
5 sed -e "s/2000/$i/" 2000.xml > $i.xml;
6 done
7
批量删除用户脚本：
1 #!/bin/bash
2 for ((a=10000;a<=200000;a++)) ;
3 do
4 i=$(echo $a)
5 rm $i.xml;
6 done
7
三.音频通话配置
/usr/local/freeswitch/conf/dialplan/public.xml||default.xml
1.一对一：
<extension name="One_on_one">
<condition field="destination_number" expression="^(\d{5,6})$">
<action application="set" data="dialed_extension=$1" />
<action application="set" data="media_webrtc=true"/>
<action application="bridge" data="user/${dialed_extension}@${domain}"/>
</condition>
</extension>
2.一对多(会议)：
1 <extension name="nb_conferences">
2 <condition field="destination_number" expression="^(\d{4})$">
3 <action application="answer"/>
4 <action application="set" data="conference_auto_outcall_flags=none"/>
5 <action application="set" data="conference_auto_outcall_caller_id_name=$1"/>
6 <action application="set" data="conference_auto_outcall_caller_id_number=$1"/>
7 <action application="set" data="conference_auto_outcall_profile=default"/>
8 <action application="conference" data="$1-${domain_name}@default"/>
9 </condition>
10 </extension>
四.视频会议通话配置
在/usr/local/freeswitch/conf/vars.xml配置支持的视频编码
259 <X-PRE-PROCESS cmd="set" data="global_codec_prefs=OPUS,iLBC,G722,PCMU,PCMA,H263,H263-1998,H264,GSM,VP8,VP9"/>
260 <X-PRE-PROCESS cmd="set" data="outbound_codec_prefs=OPUS,iLBC,G722,PCMU,PCMA,H263,H263-1998,H264,GSM,VP8,VP9"/>
配置用户路由
/usr/local/freeswitch/conf/dialplan/public.xml||default.xml
23 <extension name="cdquality_conferences">
24 <!-- <condition field="destination_number" expression="^(35\d{2})$"> -->
25 <condition field="destination_number" expression="^(\d{4})$">
26 <action application="answer"/>
27 <action application="conference" data="$1-${domain_name}@video-mcu-stereo"/>
28 </condition>
29
30 </extension>
而video-mcu-stereo是在文件
/usr/local/freeswitch/conf/autoload_configs/
230 <profile name="video-mcu-stereo">
231 <param name="domain" value="$${domain}"/>
232 <param name="rate" value="48000"/>
233 <param name="channels" value="1"/>
234 <param name="interval" value="20"/>
235 <!-- <param name="interval" value="auto"/> -->
236 <param name="energy-level" value="300"/>
237 <param name="auto-gain-level" value="2200"/>
238 <param name="caller-controls" value="none"/>
239 <!--
240 <param name="tts-engine" value="flite"/>
241 <param name="tts-voice" value="kal16"/>
242 <param name="muted-sound" value="conference/conf-muted.wav"/>
243 <param name="unmuted-sound" value="conference/conf-unmuted.wav"/>
244 <param name="alone-sound" value="conference/conf-alone.wav"/>
245 <param name="moh-sound" value="$${hold_music}"/>
246 -->
247 <param name="enter-sound" value="tone_stream://%(200,0,500,600,700)"/>
248 <param name="exit-sound" value="conference/conf-goodbye.wav"/>
249 <!--
250 <param name="auto-record" value="$${recordings_dir}/${conference_name}_${strftime(%Y-%m-%d-%H-%M-%S)}.wav"/>
251 <param name="exit-sound" value="tone_stream://%(500,0,300,200,100,50,25)"/>
252 <param name="kicked-sound" value="conference/conf-kicked.wav"/>
253 <param name="locked-sound" value="conference/conf-locked.wav"/>
254 <param name="is-locked-sound" value="conference/conf-is-locked.wav"/>
255 <param name="is-unlocked-sound" value="conference/conf-is-unlocked.wav"/>
256 <param name="auto-record" value="/home/${conference_name}_${strftime(%Y-%m-%d-%H-%M-%S)}.mp4"/>
257 <param name="pin-sound" value="conference/conf-pin.wav"/>
258 <param name="bad-pin-sound" value="conference/conf-bad-pin.wav"/>
259 -->
260 <param name="caller-id-name" value="$${outbound_caller_name}"/>
261 <param name="caller-id-number" value="$${outbound_caller_id}"/>
262
263 <param name="comfort-noise" value="0"/>
264 <param name="conference-flags" value="video-floor-only|rfc-4579|livearray-sync|livearray-json-status|auto-3d-position|transcode-video|minimize-video-encoding"/>
265 <param name="video-mode" value="mux"/>
266 <param name="video-layout-name" value="4"/>
267 <!-- <param name="video-layout-name" value="group:grid"/> -->
268 <!-- 1280x720 800x600 -->
269 <param name="video-canvas-size" value="1280x720"/>
270 <param name="video-canvas-bgcolor" value="#333333"/>
271 <param name="video-layout-bgcolor" value="#000000"/>
272 <param name="video-codec-bandwidth" value="auto"/>
273 <param name="video-fps" value="25"/>
274 </profile>
275
五.通过sip trunk跟其他产品对接
配置sip trunk网关/usr/local/freeswitch/conf/sip_profiles/external/sip_trunk.xml
1 <include>
2 <gateway name="trunk.com">
3 <param name="realm" value="xxx.xxx.xxx.xxx"/>
4 <param name="proxy" value="ip:port"/>
5 <param name="register" value="false"/>
6 </gateway>
7 </include>
配置路由/usr/local/freeswitch/conf/dialplan/public/000_sip_trunk.xml
1 <include>
2 <extension name="extension-trunk.com">
3 <condition field="destination_number" expression="^0(\d+)$">
4 <action application="set" data="dialed_extension=$1"/>
5 <action application="bridge" data="sofia/gateway/trunk.com/$1"/>
6 </condition>
7 </extension>
8 </include>
六.freeswitch在多网卡服务器下指定IP地址
修改internal.xml和external.xml
位置：/usr/local/freeswitch/conf/sip_profiles
修改内容：
64 <param name="rtp-ip" value="$${local_ip_v4}"/>
65 <param name="sip-ip" value="$${local_ip_v4}"/>
把$${local_ip_v4}改为指定的ip地址
七.权限问题
在使用sudo命令时，经常性会提示出“不在 sudoers 文件中。此事将被报告”的错误信息。
这是因为当前登录的账号不在sudo权限里面。
sudo命令可以让你以root身份执行命令，来完成一些我们这个帐号完成不了的任务。
其实并非所有用户都能够执行sudo，因为有权限的用户都在/etc/sudoers中
打开：/etc/sudoers
修改：
# User privilege specification
root ALL=(ALL:ALL) ALL
username ALL=(ALL:ALL) ALL(添加的用户)
