If this is the model I think it is, your phone line cord is pluged into the base of the main handset. So let me see if I'm understanding your problem...You have a single line phone with two handsets, and your remote handset rings, but the main handset at the base unit does not. Since your second handset rings when called,your line is working, and your unit's base is working, as well, or the other handset would not ring. Therefore your problem is within the handset itself. I will assume you've made sure the ringer is turned ON and the volume turned UP. Use the Menu button on the handset to find these variables and make sure the ringer is ON and turned UP. Place the handset on the charging cradle. Press the ON button WHILE the phone is on the cradle. You might have to use the speakerphone button to do this. This will resync your handet with its base.
