How Do I for some of my lines only to ring on certain phones? I dont want the rest of my phones to ring.

Normally tech side programming
If you do not know how to program, navigate or the password call a tech.
otherwise go to Sets/Ext#/Line Access/Line Assignment, enter line # in question, press Change until you see the option you want ie.e appear only or not assigned.

Now that's an oldie :-) I have the instructions squirreled away right here

Here's how to program line ringing:

• go to the voice terminal whose line ringing you want to program

• slide T/P switch toward you

• touch a line button (note red lights)

• touch the button again until correct code appears:

RED ON = Ring

RED FLASH = Delayed Ring

RED OFF = No Ring

• repeat this procedure for each line

• return T/P switch to center position.

Partner, all releases. Examples
Receptionist Call Routing. If you want calls to be answered by the receptionist first, set the lines at the receptionist's extension to Immediate Ring and the lines at the users' extensions to No Ring. (This is the factory setting)
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.
Programming
To change the way outside lines or pools ring at an extension:

1. Press [ Feature ] [ 0 ] [ 0 ] [ System Program ] [ System Program ] [ Central Tel Program ].
2. Enter the number of the extension to be programmed for Line Ringing. The green lights next to the line or pool buttons on the phone show the current Line Ringing settings for all lines assigned to the extension. (If a line is not assigned to a button, the green light next to the button is off.) The following ringing options can be shown by the green light next to the line button.
   • Immediate Ring - on steady
   • Delayed Ring - flashes slowly
   • No Ring - flutters quickly
3. To change Line Ringing for any line, press the line or pool button until the button light shows the correct setting (the setting for the currently selected line or pool also appears on the display).
4. Continue programming or exit programming mode.

Turn the program toggle switch on (right side of KSU), go to the phone to be programmed and press the # button, then press the line button to ring, then pick up and then hang up handset. You should hear a confirmation tone. This will affect all line buttons, even the ones not pressed. Any line buttons not pressed will not ring. Do this at each phone.

no you can not put a certain contacton silent while the other rings, yes you can put only contacts to show when your phone rings.........just change the option in your contacts/phonebook

WOW
Ok this post is OLD, but for anyone else having this issue, this is the solution...

There is a programming feature that states: DELAYED RING on certain lines, meaning you can physically see a call coming in to the system (via line flashing), but it will not ring at your desk till something like the 4th ring(hence the name DELAYED ring).

If your set does not ring, and you pick up the heandset, the phone system doesn't know if you want to answer the call -or- you just want to make an outgoing call...
Therefore the Mitel system picks up internal dialtone and waits for you to make the initial reaction (hit 9 for a line out or hit a line that is flashing on the set).

Too change this option, a Mitel Tech is required...

disconnect all phones and just connect the GE phones.
there is only a certain amount of power transmited through a phone line to make the phone ring if you have too many phones running off the same line then the ones further away from the main connection suffer
