My old job has 6 Cisco 7962G (and 1 7960G) phones set up. On each phone, the 6 Line buttons are labeled as follows:
Button 1 = 3X (The phone's extension, X ranging from 0-6)
Button 2 = Line A
Button 3 = Line B
Button 4 = Line C
Button 5 = Line D
Button 6 = Help & Support (Speed Dial)
All of the phones are part of a "ringall" group, meaning every single phone rings when a call is received. But instead of the extension line (Button 1) flashing, Line A (Button 2) flashes on all of the phones. When 1 of the 7 users picks up the call, that particular phone highlights the Line A button with a green color, while all other phones highlight that same button with a red color showing that the line is in use. And, if Line A is in use, the next received call goes directly to Line B, and so on.
Does anyone know the technical term to define this type of configuration? And/Or how to set this up? I have two 7962Gs in my house and I would prefer to have a setup just like the one described above. Not only would I like to see which line is active when in use, but I'd like to make it so that incoming calls utilize the next available line button if the first is busy, instead of sharing it across the same button.
And yes, I've tried registering the extension across 3 buttons to simulate 3 lines, but the first button is the only one that flashes when a call is received; even while in use.
I should also mention the phones at my old job use SCCP, not SIP. Not sure if that affects anything. I am fairly new to the Asterisk world.
