I have noticed phones with a handset (like the one in the image) have a little cover that resembles something like a cold camera shoe under the bottom of the handset’s top speaker holder. Is there a use for it? It has a line bump in the middle, but it doesn’t go all the way from both sides, it leaves a gap. I have also seem some of them have extra space on the top of the cover, and some don’t.

      It’s a slot on a camera that you can use to attach accessories, like a microphone or flash. A hot shoe provides power to the accessory, a cold shoe does not.

      Its a non-powered version of a hot shoe, both of which are the thing you use to mount an external flash that’s on the top of a lot of (all?) full sized cameras.

    If you’re talking about this thing, it serves two purposes. It is the hook that opens and closes the line (hangs up and picks up the phone), and it is used by this thing

    to keep the handset from falling off the base when it’s mounted on a wall.

      Or maybe you meant this thing. Yeah, it keeps the handset in when the base is mounted vertical. You can see that it’s slanted in the back.

      That’s so it slides in and out on this other slanted lip on the handset instead of getting caught on it. You can take the handset off just by pulling it directly away from the wall.

        Btw, on Trimline phones it is reversible for if you’re not hanging it on a wall. It looks like this when you pull it out.

        Exactly this. It’s called a “hook” and when the phone is “off the hook” that’s the thing it is off of. Being off the hook means the phone is powered up and connected to the local loop. When the phone is “on hook” that means it is disconnected from the loop and awaiting the pulsed ring signal.

        Desk phones have a reversible hook so that it keeps the button depressed when the phone is in the cradle but doesn’t catch when you attempt to pick it up.

        On modem signals in the old days, the + was equivalent to “flashing” the hook, or quickly disconnecting and reconnecting to the loop, and the AT command H1 told the modem to go “on hook” while H0 told it to go “off hook”.

        Back before the DTMF network, when everyone used pulse modulated phones, the “pulses” were caused by going in and off hook in a specific pattern. You could actually make a phone call from a rotary payphone by flashing the hook in the pattern that mimicked the rotary dial pulsing the line as it rotated back to home position.

        In the really old days, the hand crank served much the same purpose, but actually supplied electricity to the local loop; when the phone was on hook (which was a big metal thing the earpiece sat in) someone else turning the crank would make all the phones on the loop ring; you picked up if the ring matched the number of rings for your extension.

          Yes! Another phone nerd!

          One small clarification. There’s not really anything special to the pulses for pulse dialing. One pulse for the number 1, all the way to nine pulses for number 9, and then ten pulses for a number 0.

            In the 80s there was a way to cheat phone booths in Germany: With a small tool that had an adjustment screw you could position the hook switch to an exact position where the phone booth had already connected the line but did not yet power up the rest of the machinery (including coin counters)

            You could then call arbitrary nunbers by pulse dialing using the hook switch (the rotary dial was still powered down)

            Basically a EU pulse dial version of phreaking.

            My father, who died this year, used this a lot too make “free” calls in the 80s.

          So that’s how you used the old hand crank phones, I never know. I thought you turned the crank to get power into the phone and then told the person working the switch bord who you want is to talk to. And that when you were telling you sometimes needed to re turn the crank to get more power.

          And the even older design that didn’t even have a bell integrated in the base. The bell was in a separate bell box.

            Or one of these real old designs that didn’t even have a bell. It has a buzzer that’s barely audible (it might even just be the phone’s speaker, idk). Also, the microphone and the earpiece aren’t in a convenient handset.

            This one is a replica made in probably the 1970s or 1980s. It’s funny, when it was made it was a replica of something vintage, but now it actually is vintage.

            Interesting. I’ve never seen a phone like that. Usually the wall mounted versions of the Model 500 had a hook for the handset in the front of the base to hang the handset vertically. This one looks like a different company than Western Electric though. I’m guessing it’s a UK company, because it’s 999 for emergencies (or at least it’s not US). You’ve got me curious enough I feel like I’m about to go down a rabbit hole.

            Edit: yep, it’s a UK company called GPO. This is their model 741:

          The “shoe” is the mount. “Hot” means powered, for things like flashes. “Cold” means unpowered, for things like tripods.

                I would hazard a guess that

                1. this is just a picture of a “telephone with a handset”, not the specific thing they’re talking about, and

                2. their phone has a removable “hook” that was removed and lost sometime in the past and they’re seeing the slot where it went

    Lots of people in this thread answering the question but they’re kind of just guessing what you’re talking about.

    Perhaps you could circle the bit in question because it’s either a holder for the headset or a way to mount the entire device onto a wall or something else depending on if we’ve interpreted your words correctly.

      Edit: note that this is a “hot” shoe because it has contacts that can power accessories. A cold shoe is just a mount. You can use to to attach a flash or a microphone for example

        An old hack that not many knew was that you could tap the hang up switch to dial numbers. Example, tap 3 times = 3, tap 10 times = 0.

        Rotary phones did the same thing which is why you had to wait for the whole thing to spin back, it was tapping the line to dial out.

          20 years ago the pocketable digital cameras that took over the consumer market didn’t have hot shoes. 30 years ago the compact point and shoot viewfinders that were the weapon of choice for vacationing didn’t have hot shoes. Today neither are relevant and are all outclassed by smartphones, and there is hardly a consumer camera market.

          You don’t have to spend five figures for that exposure, but it’s going to be an intentional hobby.

    It holds the receiver in place. Generally the ridged end is used for wall hanging installs, the flat end stores it away until needed since the desk is horizontal.
