Hi, I have read that silent-calls in GSM can be used to make a call to a target MS and listen to it without having the target knowing it. Is this theoretically possible ? If yes, can it be done in OpenBSC ?
Hi, You are mislead by the name "silent call". In reality this does not make the phone transmit voice data, just a strong, high powered radio signal that could be used to locate the device/user by using it as a tracking beacon. It is possible to send a command to an MS connected to openBSC afaik that activates this feature. Cheers, Domi 2017. aug. 15. dátummal, 14:04 időpontban samir <samir.s.abed@gmail.com> írta:

Space Waves may offer customization options or unlockable content that https://spacewaves-2.io enhances personalization and variety in addition to its primary gameplay.
In GSM, there are features (often referred to as silent call, stealth call, or eavesdropping mode) that allow a network to set up a connection to a mobile station without alerting the user (no ringing or visible indication). https://motox3mgame.org
