I have purshased a used 4A speakerphone system to complete my 2565. I'm surprised because the pictures of the connecting bloc I usually seen had 3 large connectors (one with 108A+switch+black module, 2nd for the phone, 3rd for remote cable) It was also an easy way to find the power supply wires. Unfortunatly, the one I've got is a smaller connecting box with only one large connector place. As is, the other side of the cable have all the wires to connect one by one somewhere... My system is used alone at home without a key system. Can I plug the 2565 phone connector diretly to the 108A+switch+black module and just use a cable for the 2 wires of the line directly on the phone ? I also need to find the wires for the power transformer of the 4A.
