Hi! Keypad of the handset is not working! Everything seems to work ok. When I receive a call the handset ring, illuminate and display the line number but not any button on the keypad not work so I cannot answer. Same with the intercom call. With keypad not working is not possible to place any call! What I can resolve this problem? Thanks in advance

Ok IF you can answer the Call and it still continues to ring, then this is a real wired problem, Usually, the "Ring" cycle, is used to "Trigger" a "Alerting" circuit that then makes a sound, when the call is answered, this "Resets" this circuit. Now IF it does continues, to ring AFTER the handset has answered the call as normal, then obviously, either the handset, is sending the correct signal back to the base, and the base is putting the call through, BUT the Ring Circuit, isn't being Reset. The fault, then must be with the base. You will have to get it looked at. As an aside, when does it stop, I mean it must, or that would have been your query too? No? So I assume, that it does eventually, stop, I expect it would, as usually, you would design in a "Watch Dog" circuit, that would, time out, if the circuit, didn't reset itself after a pre-defined period. So, Thats the Diagnosis, you will have to repair or replace. As usual though, remove from power, reset as if new, if still faulty. You know what to do.
