[asterisk-users] Help with call scenario

[James Mutuku]

I am running asterisk and I want to achieve the following scenario

My goal in the end is to achieve the scenario (example using extension A and
Extension B)

1. Extension A has a line apperance of 4(4 calls can ring on it).
2. Extension B calls extension A(which is busy on one of the lines).
3. Extension A sees the second light blinking and hears the beeps (currently
working).
4. Extension B is notified that extension A is on another call.

Where do I start...I have looked in the following call
variables--$dialstatus and $devstatus but I can't get them working
