[Asterisk-Users] I don't know the name of this feature...

[Sean Kennedy]

Hi all, I'm still sorta new to asterisk, and somewhat new to this list.  
And I am very new to working with phone systems, so forgive me if this 
question has been answered before.

Anyway.

Currently, our office phone systems have 6 outside lines coming in.  The 
actual phones have lights ( indicators ) for these lines, so matter 
where you are in the office, you can look at the phones and see that 
someone is on line #2 ( for instance ).  I am not 100%, but I suspect 
that all of these indicators are specifically tied to a specific line.  
I know this is the case with the last 2 lines, which are tied to 
different phone numbers all together.

What is this feature called?  Can asterisk do it?

I appreciate any help anyone can offer, and I can give more details as 
needed.

Sean
