I really know very little about asterisk and telephony systems but I ended up designing one. Therefore I need your help. My first question is:
I have to call a number, for example 00 90 123 456 78 90. I am using an E1 line so I have 30 lines. Now I would like to check for a particular line whether it is available for making a call. I mean I would like to know which lines are available or busy. Then, I would like to call that number with one of the available lines.
By the way, what number the system calls can always change so, one-time configurations will not work. I mean I have to do these calls with asterisk dynamically.
Can someone show how can I do that?
Thanks in advance.
