I have an option 61C switch R25 I need to know can i setup a display button on a phone so when your talking on line 1 and line 2 rings you can see who is calling? Can anyone help me out with this? Any help would be greatly appreciated.
You can also set the class of service on the set to TDD (it's probably set to ADD now). This will automatically update the display to show the second caller when first line is already engaged.
