本文提供一个OpenSIPS的一键安装包，OpenSIPs 可以作为FreeSwitch 的前端代理，实现多个FreeSwitch 负载均衡处理呼叫流量。

以 opensips-2.1.2.tar.gz 为例

安装环境CentOS 6.x 64 bit

Step 1  Download

下载数据库配置文件 修改数据库信息

wget  https://hk-area1-file.oss-cn-hongkong.aliyuncs.com/fsgui/init.conf

下载安装脚本

wget  https://hk-area1-file.oss-cn-hongkong.aliyuncs.com/fsgui/opensips_install.sh

安装命令

sh opensips_install.sh

安装完成  opensips 自定启动

Step 2 启动

/usr/local/sbin/opensipsctl start

停止

/usr/local/sbin/opensipsctl stop

Step 3  常用命令

/usr/local/sbin/opensipsctl start

ps -ef|grep opensips

/usr/local/sbin/opensipsctl stop

ps aux | grep opensips（查看进程）

netstat -ulpn|grep opensips（查看UDP链接状态）

netstat -utpn|grep opensips（查看TCP链接状态）

/usr/local/sbin/opensips -c  检查配置是否正确

增加freeswitch 后端服务器

opensipsctl   dispatcher show

 dispatcher addgw <setid> <destination> <socket> <state> <weight> <attrs> [description]

   * Examples:  dispatcher addgw 1 sip:1.2.3.1:5050 '' 0 50 'og1' 'Outbound Gateway1'

   *            dispatcher addgw 2 sip:1.2.3.4:5050 '' 0 50 'og2' 'Outbound Gateway2'

   *            dispatcher rmgw 4

opensipsctl dispatcher addgw 1 sip:47.91.133.205:5099  ""  0 50  'us1' 'cs.wdjbp.com'

opensipsctl dispatcher addgw 1 sip:47.89.33.209:5099  ""  0 50  'us2' 'wandan.wdjbp.com'

insert into load_balancer (group_id,dst_uri,resources,description) values (1,'sip:47.91.133.205:5099','pstn=100','hk1');

insert into load_balancer (group_id,dst_uri,resources,description) values (1,'sip:47.89.33.209:5099','pstn=100','hk2');

opensipsctl fifo lb_reload

dispatcher show ..................... show dispatcher gateways

dispatcher reload ................... reload dispatcher gateways

dispatcher dump ..................... show in memory dispatcher gateways

dispatcher addgw <setid> <destination> <socket> <state> <weight> <attrs> [description]

                .......................... add gateway

dispatcher rmgw <id> ................ delete gateway

增加freeswitch 后端服务器

opensipsctl   dispatcher show

dispatcher gateways

opensipsctl dispatcher addgw 1 sip:182.92.158.206  ""  0 50  'hk1' 'hk1.wdjbp.com'

opensipsctl dispatcher addgw 1 sip:47.88.86.32  ""  0 50  'hk1' 'hk2.wdjbp.com'

SIP账号登陆前 先确保

vi /usr/local/freeswitch/conf/vars.xml

修改了vars.xml中的 domain 参数

<X-PRE-PROCESS cmd="set" data="domain=2224{local_ip_v4}"/>

改为

<X-PRE-PROCESS cmd="set" data="domain=h5.wdjbp.com"/>

FS节点需要在ACL里面把 opensips 所在IP 加入白名单

测试验证
