目的
?
1：假設(shè)一個(gè)簡(jiǎn)易的asterisk 集群，通過(guò)realtime 技術(shù)，在集中的一個(gè)數(shù)據(jù)庫(kù)中管理所有集群節(jié)點(diǎn)的分機(jī)號(hào)和撥號(hào)規(guī)則
2：asterisk服務(wù)器1上分機(jī)號(hào)段為 8100-8199
asterisk服務(wù)器2上分機(jī)號(hào)段為 8200-8299
3: 實(shí)現(xiàn)同一臺(tái)asteisk服務(wù)器上分機(jī)互打
4：實(shí)現(xiàn)同一號(hào)段分機(jī)互打
5：實(shí)現(xiàn)不同號(hào)段分機(jī)互打（由kamailio服務(wù)器轉(zhuǎn)發(fā)）

配置

1：asterisk服務(wù)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/extensions.conf
[internal]
switch => Realtime/internal@extensions ; edit by tolooney
?
[root@localhost asterisk]# cat /etc/asterisk/sip.conf
[general]

2：asterisk服務(wù)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

sippeers => mysql,general,ast_sipfriends ; edit by tolooney
extensions => mysql,general,ast_extensions_02 ; edit by tolooney

allow=ilbc
?
?
備注：分機(jī)號(hào)存放在ast_sipfriends表中，撥號(hào)規(guī)則分別存在ast_extensions_01，ast_extensions_02..表中
