Ok, I maybe loosing it here.. But I am gonna give it a shot anyways.

System: IDCS-500 R2
Using a 16DLI (one of a many available)

Connected DPIM Line to Available DLI Port.
Connected KP-200 to DoorBox port on DPIM
Followed the "Wiring" specs in install manual..

RJ-11 Pin #1 (Yellow) to L2
RJ-11 Pin #2 (Green) to L1
RJ-11 Pin #3 (Red) to P+
RJ-11 Pin #4 (Black) to P-

Setup MMC211 to ring my local Extension, All Ring Plans.
Setup Timer to 25*5msec
Press "Call" Button from Door Phone, Rings My Local Extension, I press "ANS/REL" and get option for "OPEN" .. If I press "OPEN" I the relay clicks for the designated time. good.

Now, Here is what I can't figure out.. I have NO 2 WAY AUDIO.. I can't here anything @ the DoorPhone, or on my KeySet.. Its like someone pressed Mute on both ends?

I have tried 2 KP-200 Doorphones, and 3 DPIM Modules. I am going to try another DLI port on another System Next. But I am at a loss?? I have trippled checked everything.

There is no way these all can be bad?

Wtf? Samsung use some _other_ standard for wiring?

Pin1->Yellow->P-
Pin2->Green->P+
Pin3->Red->L2
Pin4-Black->L1

Red light works on Doorphone, 2 way audio works.

Your right. You probably had it wired wrong. It is a little strange on the pinouts.

Thanks for the information here. I just came across a client with the same compliant. Didn't have time to trblshoot it. Gonna check it tomorrow, so this tip is handy.
