Elastix 2.5的系统是Centos 5.9,Asterisk 11。在测试dialpan拨号方案使用odbc mysql的时候报错驱动/usr/lib64/libmyodbc3_r.so找不到,经验证是系统的mysql-connector-odbc没有安装。

在通过yum安装的时候又发现源已经停止服务了,无法下载,找到一个国外源fq下载完,在另外一台机子上则是选择本地安装yum包,下载地址:

https://centos.pkgs.org/5/centos-x86_64/mysql-connector-odbc-3.51.26r1127-2.el5.x86_64.rpm.html  (x64)

https://centos.pkgs.org/5/centos-i386/mysql-connector-odbc-3.51.26r1127-2.el5.i386.rpm.html (x86)

下载完后可以放到当前目录 shell执行:

yum -y localinstall mysql-connector-odbc-3.51.26r1127-2.el5.x86_64.rpm

安装完成后还需配置/etc/odbc.ini:

[MYSQL-asteriskcdrdb]
Description = MySQL connection to 'asterisk' database
Driver = MySQL
Database = asteriskcdrdb
Server = localhost
Port = 3306
Socket = /var/lib/mysql/mysql.sock
User = root
Password = MyPass
Option = 3

配置完成后可以在shell中测试:

[root@Elastix ~]# isql -v MYSQL-asteriskcdrdb
+---------------------------------------+
| Connected!                            |
|                                       |
| sql-statement                         |
| help [tablename]                      |
| quit                                  |
|                                       |
+---------------------------------------+
SQL> show tables;
+-----------------------------------------------------------------+
| Tables_in_asteriskcdrdb                                         |
+-----------------------------------------------------------------+
| cdr                                                             |
+-----------------------------------------------------------------+
SQLRowCount returns 1
1 rows fetched

这就算完成了一半,还需在/etc/asterisk/res_odbc.conf中配置dsn:

[asteriskcdrdb]
enabled=>yes
dsn=>MySQL-asteriskcdrdb
pooling=>no
limit=>1
pre-connect=>yes
share_connections => yes
isolation => repeatable_read
forcecommit => yes

在/etc/asterisk/func_odbc.conf中配置自定义函数(此处dsn指res_odbc.conf中的[name]):

[SQL]
dsn=asteriskcdrdb
readsql=${ARG1}
synopsis=ODBC_SQL(sql)

具体配置说明详见:https://wiki.asterisk.org/wiki/display/AST/Getting+Asterisk+Connected+to+MySQL+via+ODBC

http://www.asteriskdocs.org/en/3rd_Edition/asterisk-book-html-chunk/getting_funky.html

配置完后注意在Asterisk CLI中执行reload或者shell执行:

asterisk -x reload

最后就可以在dialpan中测试使用了,如下面的例子(/etc/asterisk/extensions.conf)拨打876在asterisk日志中输出结果:

[from-internal]
exten => 876,1,Answer
exten => 876,n,Noop(${ODBC_SQL("select now()")})
exten => 876,n,Noop(${ODBC_SQL("select top 1 uniquid from cdr order by calldate desc")})
exten => 876,n,Background(star)
exten => 876,n,Wait(60)
include => from-internal-noxfer
include => from-internal-xfer
include => bad-number ; auto-generated
