I know this is basic, but I have limited voice experience.
We have CUCM System version: 184.108.40.206900-2
I have a 7960 phone that currently has two existing extension numbers. I want to remove those numbers and replace them with two different existing extension numbers.
Should be pretty simple.
I went to the phone requiring the changes and selected "Modify Button Items" from the configuration page. I moved the line I want to remove from the "Associated Items", over to the "Unassigned Associated Items", then disassociated the line.
The line was removed.
The problem is adding the new line, I am running into trouble.
I have the line associated to the phone, but I am unable to move the line from "Unassigned Associated Items" over to the "Associated Items" column on the "Modify Button Items" page.
