I have a customer that has an ESP and his staff keeps using dialing 9 for an outside line instead of using that outgoing button. This is causing an issue because 911 keeps getting called and the sherriff's office isn't happy. I know that the outgoing button is in a line group that sounds like the same as dialing 9. Can I disable the 9 without taking away the line group for the outgoing button?
Thanks in advance, no one in our office is an expert on this system!!
