can asterisk make a certain line ring on a phone. here’s the setup. there are 3 lines that go into the server. i have aastra 480ict phones. I was asked if when someone calls line 1 on the hard lines if it will ring line 1 on the sip phones, if they call line two if it will ring line two, and so on. also that when line one is pressed you dial on line one, when two on two, ect. i know how to dial a specific line out by pressing the line and assigning it to open the line first. but is it possible that when the lines ring that the corrasponding line will light up on the phone?
