The old one has faint colors. From what I can tell from the top there are white, blue, green, gray, yellow and brown in sequence. Verify them. In any case, from the top you have: microphone - MIC mass - MASS handset - SPK call - RING button - SW1 button - SW2 Jumpers according to the instructions.
Gentlemen, the problem is that the old intercom was connected to two wires, the plus was yellow, the minus was blue, I have 8 wires at my disposal, yellow, blue, white, brown, black, red, green and orange, how to handle it all, I found one diagram, I connected it as in the picture, you can hear crackling in the handset, and yet you can't hear anything when someone calls downstairs
