Greetings. There is a cable that comes from the intercom green, black, brown, orange white and blue (black and brown were not connected) and from the router (Partner's phone cable) comes out yellow, green red, black. I would be happy to help which color for which color. Just remember that before it was cut 2 cables were connected on one side to 2 cables on the other side and another 2 cables together for a pair of cables opposite. See photo.Thanks
