Hello, friend:
you have to install asterisk and download a sip phone such as xlite.
there are few things, which you have to do:
learn to write simple dialplan.
create sip account, for example.
know the extensions.conf, sip.conf.
later you can learn AGI, and asterisk manager command. by the way, of course, you have to learn linux first. it's better that you install centos 4 or later version.  there are few websites that you always can go:
asterisk.org, voip-info.org, asteriskguru.com.
try it and enjoy it.
regards!

Thank you.
Which English forum site is better? we need more guru to answer question for the beginner!

hello, friend:
it is a good news for you to start learning asterisk. but i suggest that you download the free books first. you always can access this two website, which are good and are my lecturers. the two URLs : asteriskguru.com and voip-info.org. the asteriskguru tells you the basic things with pictures. of course, you can get deeper understanding from voip-info.org. there are many things and issues about asterisk and other PBX. you have to try to push yourself to learn how to ask a question in asterisk.org. this website is offical asterisk website. you can post your question to there. the asterisk guys are very supportive for users. keep in mind that posting questions with bugs and .conf there. later you will be a good asterisk developer!
good luck!

学习asterisk，首先从基本开始，由于asterisk的代码非常的散乱，甚至可以说是不规范，所以应该从玩开始，先学会配置，玩起来，再去思考，如果是做开发，当然从行为去分析asterisk代码是一个不错的选择。

请说说怎么去分析代码！ 什么样的方法比较快一些。 我现在也在看代码，把我们用到的函数看了看，但是总体的框架还是不大清除阿，比如一个电话呼叫另一个电话，应该调用什么样的函数==了

app_dial.c函数中的dial_exec函数，至于总体框架，不是一下就能清楚的，有些人做了2年也不清楚，看你的目的是什么，看代码要结合试验，一个电话是怎么样打通的，比如sip，从do_monitor,sip_sockread到生产一个channel，启动一个channel。到PBX CORE 执行一个channel的exec，找到DIAL，发现DIAL对应的app回调函数。。。先慢慢看吧

请问这些在代码的执行过程是什么啊， 前面我有点了解了。
