The intercom on my AT&T MLS-12 will not ring when called.

Changing ringing on a Partner system is done on either ext 10 or 11.
At one of those ext's press the feature key and "00"
Next press the left hand intercom twice
The display should say system programming

Press the right hand intercom once. The display should say Central telephone Programming.

Enter in the extension number that you want to program.

Press the line that you want to ring.
A solid light on the line means immediate ringing
A slow flashing light means delayed ringing (meaning the phone will wait 3 rings before starting to ring.)
A fast flashing light means no ringing.

When finished with that station press the right hand intercom and enter in the next extension to program and set ringing accordingly.

While your on the line with the caller, press the Transfr button(above the hold key) then enter in the intercom number of the person you wish to transfer the caller to. You can either wait for the person your transfering the call to to answer his extension before you tranfer the call or you can hang up after you enter the intercom number, either way, when you hang up the phone after entering in the intercom number, the call is transfered to the extension.

First of all, is it programmed to ring? From Ext 10 or 11 press FEATURE 00 LIC LIC RIC and dial the extension you want to look at programming. The line buttons will light up. They will be SOLID for RING, SLOW BLINK for DELAY RING, or FAST BLINK for No Ring. Just keep pushing each line button until you get what you need. When you're done, press FEATURE 00.

LIC is LEFT INTERCOM RIC is RIGHT INTERCOM button.

Easy enough :-)

It sounds like the HFAI button on most of the sets is turned off. the HFAI (hands free answer intercom) button is located to the right of the SPKR key. With the handset down press the HFAI button. The green light next to it should light indicating that it is active. If the power goes out or if the phone is unplugged it will return to HFAI off status. hope that helps.
