    It's a gas discharge tube- transient voltage protector.

    you should google all variants:

    transient arrester, transient arrestor
    surge arrester, surge arrestor

    according to wikipedia, there are many kinds:

    But arrestor is more common actually.

    A device similar, is used in non-thyristor electronic photo strobes, and there called a "quench tube"... part of the charge on the main capacitor that isn't used for the flash, turned off by a phototransistor circuit, is redirected to the quench tube, and does not illuminate the photo...

    Looks like a professional grade phone equipment surge arrestor, the cheaper glass tube variety are often found in CDI gas igniters.

    I have some larger ones rated a few kV that were found protecting the focus circuitry on a Hitachi Studio 19 Sun monitor.

    The phone ones are usually rated around 220 - 230V ish.
