When on a call and another line rings, how do I get the ringing to stop?

If you have a landline, most likely you have a short in it. Not enough to kill line, but, when the 90 volts a.c. comes in to ring it jumps short. The short answers the phone.. It doesn't stop out going but can cause static. Check the line at the box outside. if bad there call your phone company, if good there, trouble is in house

This is tech side programming known as Configuration, clients usually call in a tech/vendor for this.
You need to find out the password and know how to navigate the system programming, do F**266344 and enter the password.
Navigate to Sets, add line in question , assign ring type.

Receptionist Backup. If you want all calls on a line to ring directly at users’ extensions -with the receptionist providing backup -set the line at the users’ extensions to Immediate Ring. Then set the line (or lines) at the receptionist’s extension to Delayed Ring. An incoming call that is not answered by a user within 20 seconds will also ring at the receptionist’s extension.

then enter your extension number 2 times. So if you are extension 20, do this:
Feature11-20-20

5 Miles! Wow.. after about 300ft.. i have had problems it is because of the drain on the line i am really surprised that a low voltage current could even carry that far i would recommend you get a telephone line amplifyer to solve this problem.

I assume it does not ring but just beeps to let you know another line is ringing in case you want to put the current call on hold and answer it. It's called Off-Hook Call Announce, you want to have that option turned off on your extension or possibly the entire system. Do you have someone at your location that makes programming changes to the system or do you pay a company for that?
