Is it a leak if it’s a necessary technical part to a functionality?
The main issue is that it’s not obvious to non-technical users. They can’t asses what sharing IP address means either though.
The reason Telegram leaks a user’s IP addresses during a call is that, by default, Telegram uses a peer-to-peer connection between callers “for better quality and reduced latency,” Telegram spokesperson Remi Vaughn told TechCrunch.
“The downside of this is that it necessitates that both sides know the IP address of the other (since it is a direct connection). Unlike on other messengers, calls from those who are not your contact list will be routed through Telegram’s servers to obscure that,” Vaughn said.
To avoid leaking your IP address, you have to go to Telegram’s Settings > Privacy and Security > Calls, and then select “Never” in the Peer-to-Peer menu, as shown below.
Telegram defaults to using p2p for calls, for contacts only.
It’s not a thorough privacy default, but otherwise seems fine to me. If you want p2p it needs to be enabled, and if you don’t it needs to be disabled. No-contacts and no-calls receive no IP.
The relevant gist is
- The information is usually not identifying beyond general geographic regions (at best)
- if your threat model is that strict, there are other ways you should be obfuscating your IP than relying on VPNs, ISPs, and the apps/servers you’re accessing/using.
Usually it is the town, or nearby town. If you live in a more rural area that can narrow it down to a few hundred people.
Also in some less-developed countries the data protection by ISPs is very weak. Basically if you know someone in the police (or pay a bit under the table) you can easy get the exact name and address of the account owner if you have an IP.
Here is an alternative Piped link(s):
Piped is a privacy-respecting open-source alternative frontend to YouTube.

I agree. This requires the user to actually save the attacker phone number as contact in order for this the IP address to “leak”
There’s still a chance that your contacts would have been hacked, and one could be vulnerable. But it all comes back to your risk profile. If you require hiding your IP address, you should turn this off or even use a VPN for all your traffic.

Ohh no, Someone on the Internet that I’m communicating with has access to a piece of information that is necessary for communicating with me.

Should have used the word direct, but their point stands.

Direct messages either use an IP to deliver them or aan alias, like email gat is identifying too. In the case of an alias, it needs to be routed through a provider, but still needs to be routed to you.
All methods of direct communication require some form of address. The question is whether giving an IP address is more or less secure than other aliases. Direct IP connection cuts out a third party being involved in routing, so one less point of compromise, but if you have a static IP, it can be used ongoing to track you or hack you in theory.

The flipside is an IP address which for users often changes is less of a security risk than someone knowing some personally linked data like a phone number, address or email that you use consistently.
You seem to be arguing for the sake of it and missing the point entirely.

We’re not directly communicating. A phone call over IP is direct.

But I could include an image in this message and get your IP address easily. It’s just worthless

Telegram not being part of Western Intelligence Toolkit along with facebook, google, apple and others offends people to the extreme, so they make a hill out of moles. P2P is inherently privacy friendly and your IP is most likely going to geolocate to the ISP. Techcrunch seems retarded.
But do keep up the fearmongering going.
Leaking ip’s is meh, however sharing info with feds while mentioning not doing this very thing in their own FAQ is shady AF. Then we have their serverside being proprietary garbage, plus intrusive info collection (like why do they need no know my hostname, device model, desktop environment, etc?). Did I mentioned they started advertising crap based on the channels a user’s subscribed to? Yeah, telegram still sucks when it comes to privacy, and it’s only getting worse over time

This is the best summary I could come up with:
The popular messaging app Telegram can leak your IP address if you simply add a hacker to your contacts and accept a phone call from them.
TechCrunch verified the researcher’s findings by adding Simonov to the contacts of a newly created Telegram account.
Simonov then called the account, and shortly after provided TechCrunch with the IP address of the computer where the experiment was being carried out.
The fact that Telegram leaks your IP address to people in your contacts during a voice call has been known for years, but it’s likely that new, less technical users may not be aware.
Simonov, who founded the cybersecurity firm T.Hunter, told TechCrunch: “Telegram focuses on security and privacy, however, in order to stay safe you need to be aware of the nuances of how the messenger’s voice calls work.”
To avoid leaking your IP address, you have to go to Telegram’s Settings > Privacy and Security > Calls, and then select “Never” in the Peer-to-Peer menu, as shown below.

The way they try to defame telegram lmao
Thanks for this, I was unaware.
Calls turned off completely now.
