做一个最基本的SIP以及IAX之间互相正常通信的测试。这对Asterisk的工作以及通信流程的了解相当有帮助。
一.配置Asterisk相关文件：
这里的配置我只是列出自己的定制部分，其他部分就不贴出来了。
1.IAX配置文件
[root@asterisk-test1 ~]# vi /etc/asterisk/iax.conf
-------------------------------------------------------------------------------------
[iax](!)
type=friend
context=test
disallow=all
allow=gsm
qualify=yes
host=dynamic
transfer=no
auth=md5
[8801](iax)
username=8801
secret=123456
context=test
[8802](iax)
username=8802
secret=123456
context=test
-------------------------------------------------------------------------------------
2.SIP配置文件
[root@asterisk-test1 ~]# vi /etc/asterisk/sip.conf
-------------------------------------------------------------------------------------
[sip](!)
type=friend
host=dynamic
disallow=all
allow=gsm
context=test
[9901](sip)
username=9901
secret=123456
[9902](sip)
username=9902
secrest=123456
-------------------------------------------------------------------------------------
3.配置拨号方案
[root@asterisk-test1 ~]# vi /etc/asterisk/extensions.conf
-------------------------------------------------------------------------------------
[test]
exten => _880X,1,Dial(IAX2/${EXTEN},,r)
exten => _990X,1,Dial(SIP/${EXTEN},,r)
-------------------------------------------------------------------------------------
二.进入控制台调试：
[root@asterisk-test1 asterisk]# asterisk -crvvv
-------------------------------------------------------------------------------------
