Question

In asterisk/elastix/freepbx, how do you....

1- detect an incoming call

2- read the caller id

3- do something...(perform function)

?

Answer 1

在“传入”上下文中，您可以检查传入呼叫的​​callerId，如果callerId匹配，则可以执行dailplan或使用AGI所需的操作

Answer 2

My general advice: read Asterisk book . It will give you most answers.

1. Calls to your asterisk will land in some context, probably incoming , but you can define different contexts for different callers.

2. There is function callerid , you can use it in your dialplan or AGI scripts

3. I use AGI scripts written in Python (there are libraries for Python, Perl and other popular languages), which connect to CRM WebService, check caller group by callerid and can prompt differently if call is from me or other employee and differently if one our customers is calling. Different prompts are in different contexts and AGI only set some variables.
