Does a Telegram Call Show Your IP Address?

call Two routes for the same encrypted audio

A voice or video call has to move a continuous stream between two devices. Telegram can do that in two ways, and which one is used depends on a setting rather than on conditions.

Directly, device to device. It is the shortest path, which is good for the call — slightly less delay, slightly fewer things to go wrong. It also means each device connects to the other's network address, and a network address is roughly a location: a city, an internet provider, sometimes a workplace.

Through Telegram's servers, which relay the encrypted stream. Neither device learns anything about the other's connection, because neither one is talking to it. The audio is still end-to-end encrypted, so the relay is passing material it cannot read.

That is the whole of the trade: a small amount of call quality against whether the other party can infer where you are. For a call with your mother it does not matter. For a call with somebody you met in a group ten minutes ago, it is the entire question.

rule Two different settings on the same screen

They sit next to each other and people change the wrong one, so it is worth separating them clearly.

Who can call me decides whether the phone rings at all. Closing it to My Contacts removes cold calls entirely, which is the more common annoyance and the more obvious fix.

Peer-to-peer decides the route once a call is connected. It only matters for calls that happen, which is why the two settings are complementary rather than alternatives: the first reduces how often the question arises, the second decides what happens when it does.

The combination worth having is both at My Contacts. Strangers cannot ring you, and if you do end up on a call with somebody outside your contacts — through a group, or because you added them for one conversation — the route is the relayed one by default.

verified_user The four emoji, and what they prove

During a call, both people are shown four emoji derived from the key their devices agreed. If you and the other person see the same four, no third party inserted themselves into the exchange.

Checking takes five seconds: say yours aloud and have them confirm. It has to be done in the call itself — comparing screenshots afterwards, or over a chat, defeats the purpose, since that is a different channel that could be the compromised one.

Be precise about what a match establishes. It says the encryption is between the two devices and nothing sat in the middle. It does not say who is holding the other device, whether they are recording, or what they will repeat later. It is the same boundary Step 025 drew for Secret Chats, in a different form — and those use a key image rather than emoji, which is worth knowing so the two are not confused.

For almost every call this is unnecessary, and that is a fine reason not to do it. It exists for the small number of conversations where you would want to be certain, and the point of knowing about it is being able to use it on the day one of those happens.

gpp_bad Calls from people you do not know

An incoming call is the most effective pressure device on this platform, and that makes it the preferred tool for a particular kind of fraud. The pattern is consistent: somebody claiming to be from a bank, an exchange, a delivery company or a support desk, asking you to act now.

The defence has nothing to do with encryption and everything to do with a habit. Hang up and contact the organisation yourself, through a number or an address you already had. Nobody legitimate is harmed by that and every impostor is stopped by it.

Three specific things never to do on a call you did not initiate: read out a code that arrived by message, install anything, or share your screen. The last one is worth naming because it sounds harmless — Step 068 covers screen sharing, and the short version is that no genuine support process needs to watch your banking session.

And if the call was unexpected at all, the routing setting is doing its job in the background: with peer-to-peer at My Contacts, answering a stranger's call gives away nothing about where you are, which removes one consequence from a moment where you are already off balance.

touch_app Try it now — five minutes

Two settings, one habit and one rehearsal.

1. Open Privacy and Security, then Calls Set who can call you to My Contacts. This is the change you will actually notice, because it removes cold calls.
2. On the same screen, set peer-to-peer to My Contacts It is a separate line and easy to miss. This is the one that closes the location question for calls with people you do not know.
3. Make one call and look at the four emoji Find them in the corner of the call screen. Knowing where they are is the whole preparation; you will not be hunting for them on the day it matters.
4. Decide your rule for unexpected calls now Decline, ask in writing, and call back on a number you already had. Deciding in advance is what makes it work under pressure.

video_camera_front Video adds a second thing to check

Everything above applies to voice and video equally. Turning the camera on adds a question the settings cannot answer: what is behind you, and who else is in the room.

The frame shows more than you think at the moment you accept a call — a whiteboard, a screen, paperwork on the desk, a window that says which building you are in, somebody walking past who did not agree to be on a call. None of that is a privacy setting; it is a two-second look before you enable the camera.

One behaviour is worth knowing because it surprises people: minimising the call or switching to another app does not switch the camera off. The stream continues while you go and find the document you were asked for, and whatever the camera is pointing at goes with it. If you need to leave the frame, turn the camera off rather than relying on the app being in the background.

And the same question applies to the audio: a call takes in the room, not just your voice. That is the reason the safest place to take an unexpected call is not the room where other people are talking.
