In his pursuit to wrench a simple and officiate Twitter app into X , the everything app that does n’t do anything very well , Elon Musk launch audio and video career on ecstasy last workweek — and this new feature film is switched on by default , it leaks your IP address to anyone you talk with , and it ’s fabulously confusing to figure out how to limit who can call you .
In a post on Wednesday , X ’s official word accountannounced the fresh feature of speech : “ audio and television calling are now uncommitted to everyone on X ! who are you calling first ? ” ten drop a line .
We looked at X ’s official aid heart page and hunt down tests of the feature to canvass how the calling feature whole kit and to sympathise the risks assort with it .
A someone ’s IP address is not enormously tender , but these online identifiers can be used to derive locating and can be linked to a individual ’s on-line natural action , which can be dangerous for high - jeopardy drug user .
First of all , the audio and video name feature is inside the Messages part of the X app , where a phone picture now appear in the top proper - script corner , both on iOS and Android .
Calling is enabled by nonpayment in the X apps . The caveat is that you’re able to only make and receive call on X ’s app , and not yet in your web browser .
By default option , calls are compeer - to - peer , which entail that the two hoi polloi in a call share each others ’ IP address because the call connects to their devices straight . This materialize by pattern in most electronic messaging and calling apps , such as FaceTime , Facebook Messenger , Telegram , Signal , and WhatsApp , as we reported in November .

Inits prescribed help essence , X says that call option are root peer - to - peer between exploiter in a way that IP addresses “ may be visible to the other . ”
If you want to veil your IP address , you may sprain on the on/off switch “ raise call privacy ” in X ’s Message mount . By flip on this background , X says the call “ will be relay through X base , and the IP destination of any party that has this setting enable will be block out . ”
X does n’t refer encryption in the official aid snapper page at all , so the calls are probably not end - to - final stage encrypt , potentially appropriate Twitter to hear in on conversations . End - to - conclusion encrypted apps , Signal or WhatsApp — prevent anyone other than the company and the recipient from listening in , include WhatsApp and Signal .
We asked X ’s press e-mail whether there is end - to - end encryption . The only reception we got was : “ Busy now , please delay back later , ” X ’s nonremittal motorcar - reception to media inquiries . We also emailed X interpreter Joe Benarroch but did not hear back .
Because of these privacy risk , we commend switch off the calling feature completely .
In case you do need to habituate this call feature , it ’s authoritative to understand who can call you and who you’re able to call — and look on your setting , it can get very puzzling and complicated .
The default scene ( as you may see above ) is “ People you follow , ” but you may choose to alter it to “ People in your address book , ” if you shared your contacts with X ; “ aver users , ” which would allow anyone who pay for X to call you ; or everyone , if you would like to get junk e-mail calls from anyrando .
TechCrunch decide to test several dissimilar scenarios with two decade accounts : a newly produce run account and a long - standing real bill . Using unresolved source internet analysis prick Burp Suite , we could see the web dealings flowing in and out of the X app .
Here are the results ( at the time of composition ):
The connection depth psychology shows that X built the calling feature using Periscope , Twitter ’s livestreaming serving and appthat was discontinued in 2021 . Because X ’s career uses Periscope , our web analysis demonstrate the X app creates the call as if it were a live Twitter / X program , even if the content of the call can not be get word .
Ultimately , whether to use X calling is your choice . you’re able to do nothing , which potentially exposes you to calls from people you probably do n’t need to get calls from and can compromise your privacy . Or you’re able to seek to limit who can call you by decipher X ’s configurations . Or , you may just switch off the feature altogether and not have to worry about any of this .
