    The red thing is a "zenamic" or equivalent. its a high value resistor that breaks down into low value when the voltage across it goes beyond its threshold value. Its a voltage peak limiter/surge suppressor.

    AKA varistor.

    The small glass body component has printed TV5 on the PCB and it`s symbol is two arrows pointing to each other. Another surge suppressor IMO.

    Depends on its use in the circuit, and your phone system. As for voltages, at my house it's 55volts on hook, 6 volts off hook, and 100volts ring.
    Your mileage may vary.
