Time wired doorbell rings

Can anybody tell me how long the existing wired doorbell is supposed to ring when the Ring unit button is pressed (it’s an old fashioned bell/buzzer that used to sound for as long as the old doorbell button was pressed). Ring phone support are completely clueless and make up numbers (started by saying 5 seconds. Then ‘it’s a pulse’ and then 1 second) . I am finding that my doorbell rings for only approx 1 second (ie Ring unit sends power to the doorbell for approx 1 second). This is too short to be easily heard. I am keen to understand if this a fault or part of the design (in which case the design is dreadful).
