I believe you have to reset the intercom system, meaning you need to reassign one or all of the phone's intercom numbers. To assign intercom # ( found on page 10 of the manual which you can download online)

1 Do NOT lift handset
2 Press the following 3 buttons (in order) PROGRAM, STAR, and then POUND
3 Enter two digits (the number you want the phone to be)
4 Press the INTERCOM button and you will hear a tone - then youre all done.

Press PROGRAM
Press *
Press #
Enter 2 digits (11 through 22)
Press INTERCOM

This should work.

SOURCE: Want to turn the ringer off unless receiving a transfer.

This feature determines how each outside line or pool assigned to an extension rings. You can specify Immediate Ring, Delayed Ring (telephone rings after a 20-second delay), or No Ring. Delayed Ring is useful for backup coverage on shared lines or pools, such as for secretaries who cover each other’s lines. No Ring is useful for all extensions except 10 when an operator answers all calls, or for telephones with no regular users, such as those in conference rooms. To change the way outside lines or pools ring at an extension:
To change the way outside lines or pools ring at an extension: 1 Press "Feature" , "00", "System Program ", "Central Tel Program" at extension 10 or 11.
2 Enter the number of the extension to be programmed for Line Ringing. The green lights next to the line or pool buttons show the current Line Ringing settings for all lines or pools assigned to the extension. (If a line or pool is not assigned to a button, the green light next to that button is off.) The following ringing options can be shown by the green light next to the line or pool button: • Immediate Ring — on steady • Delayed Ring — flashes slowly • No Ring — flutters quickly • Immediate Ring is the factory setting for lines; No Ring is the factory setting for pools.
3 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.

Sounds like you'll need to setup the intercom number again.

Assign an Extension Number to Your Phone
1 Press program.
2 Press the down arrow until the screen displays EXTENSION NO, then press the right arrow.
3 Press the down arrow or the up arrow to select the desired extension number (from 11 to 22).
4 Press the save button to store your selection.
NOTE: If you duplicate an extension number, you will hear a repeating
short ring. Repeat Steps 1-4 and assign a different number (from 11 to 22).
