目的
1：假设一个简易的asterisk 集群，通过realtime 技术，在集中的一个数据库中管理所有集群节点的分机号和拨号规则
2：asterisk服务器1上分机号段为 8100-8199
asterisk服务器2上分机号段为 8200-8299
3: 实现同一台asteisk服务器上分机互打
4：实现同一号段分机互打
5：实现不同号段分机互打（由kamailio服务器转发）
配置
1：asterisk服务器1
[root@localhost asterisk]# cat /etc/asterisk/res_config_mysql.conf
[general]
dbhost = 192.168.1.30
dbname = asterisk
dbuser = root
dbpass = luckytuo@gmail.com
dbport = 3306
[root@localhost asterisk]# cat /etc/asterisk/extconfig.conf
[settings]
sipusers => mysql,general,ast_sipfriends ; edit by tolooney
sippeers => mysql,general,ast_sipfriends ; edit by tolooney
extensions => mysql,general,ast_extensions_01 ; edit by tolooney

[root@localhost asterisk]# cat /etc/asterisk/sip.conf

allow=ilbc
2：asterisk服务器2
[root@localhost asterisk]# cat /etc/asterisk/res_config_mysql.conf
[general]
dbhost = 192.168.1.30
dbname = asterisk
dbuser = root
dbpass = luckytuo@gmail.com
dbport = 3306
[root@localhost asterisk]# cat /etc/asterisk/extconfig.conf
[settings]
sipusers => mysql,general,ast_sipfriends ; edit by tolooney
sippeers => mysql,general,ast_sipfriends ; edit by tolooney
extensions => mysql,general,ast_extensions_02 ; edit by tolooney
[root@localhost asterisk]# cat /etc/asterisk/extensions.conf
[internal]
switch => Realtime/internal@extensions ; edit by tolooney
[root@localhost asterisk]# cat /etc/asterisk/sip.conf
[general]
context=internal
rtcachefriends=yes
disallow=all
allow=ulaw
allow=ilbc
备注：分机号存放在ast_sipfriends表中，拨号规则分别存在ast_extensions_01，ast_extensions_02..表中
