My Avaya partner 18d phone will only answer and make calls on speaker. It is a new phone and it has been like this since I plugged it in.

SOURCE: Avaya Partner-18D office phone-After an intercom call, the receiver's phone rings

Try hitting the speaker button and intercom your boss. When you hit the speaker button to hang up, do you get the same thing? If not. It could be that the gray "clicker" switch that pushes down when you put the handset back isnt going all the way back down...

Let me know.

My guess is that the wires from the phone system are not connected to the jacks you are plugging into. But to verify, try plugging a display phone into the same jacks. That will prove the theory.

If that is the case you will need to connect the new phones into the phone system.

Get yourself 2 alkaline AA batteries, keep the power on, and look for the door on the lower part of the face on the ACS processor module. Pop the cover and replace the batteries.

Press Feature 00 (zero, zero) from station 10 or 11. Press left intercom button twice, press #103, and then enter time in military format (24 hr). Press feature 00 again. This is all done with the handset down.
