Question about AT&T ATT-974 Corded Phone
Extension 11 - which is supposed to be the main line - receives intercom rings from various extensions without the extension initiating them.
I have the same setup in a small office I consult for and I found the intercom problem to be caused by the DSL filters. It seems the DSL filters also filter out the frequency that the phones use to communicate with each other. If any of the phones had a DSL filter on them the intercom and hold button would not work properly with the other phones in the system without filters. Once I took the filters off the intercom and Hold function worked fine.

Tips for a great answer:
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
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.
For incoming calls, the line selection (hunt sequence) is set by the local service provider). For outgoing calls....again....it depends on the system. For the Partner ACS:
1) Press FEAURE 00, SYSTEM PROG, SYSTEM PROG, CENTRAL PROG at extension 10 or 11.
2) Enter the number of the extension to be programmed for Automatic Line Selection.
3) Press **.
4) Press the line, pool, or INTERCOM buttons in the desired order. The valid entries for Automatic
Line Selection depend upon the type of extension:
? Key Extension: Outside system lines, Left Intercom (the factory setting)
? Pooled Extension: Pool 880 button 1, button 2, Left Intercom, Right Intercom (the factory
setting), Pools 881-883, individual lines
For each button pressed, a display similar to the following appears:
Automatic Line Selection
5) To exit Automatic Line Selection, press **.
6) Press CENTRAL PROG and enter a new extension number, or exit programming mode.
Changing line ringing and line selection are tasks that are normally reserved for the Administrator of the telephone system.
