DTMF tones are emulated/regenerated by the providers and some people’s voices triggers the DTMF regeneration which leads to that dialing tone we often hear, identical to the sound of pressing a key.ĭTMF talk-off problem is common not only on mobile networks (2G/3G/4G) but also on VoIP (internet telephony) networks. DTMF (dual-tone multi-frequency) talk-off represent those situations when the phones system recognizes the recorded sounds (most commonly, female voices) as being dialing tones. It sound from sci-fi or comedy movies but it’s true. The “solution” is for that person to speak at a lower pitch. In most cases, this problems are being caused by female voices which is at a higher intensity, which sometimes match the network’s frequency for triggering dialing tones. Specifically, when someone talks and the sounds they make match certain frequencies, they trigger those dialing sounds we hear. ![]() it’s not that old tone being heard after a minute passes present on some operators systems Īfter discussing about this issue with a telecom engineer it seems that this problem is being caused by some network errors.our calls are not listened by FBI/CIA so we can hear strange sounds I know many of you think to this possibility but even if they would bug your phone to track your calls, they would make sure you won’t notice it.the other persons proximity sensor do not work, consequently keeping the screen on and unlocked.the other persons do not hold the phone to their ear as they should to cover the proximity sensor and the screen remaing on and unlocked.the other person uses an old phone with hard buttons and hits those keys by mistake.We can exclude the following possibilities which could lead to hearing dialing pads being hit durning our calls: If we don’t know this is a common problem, then we are tempted to blame the other for hearing those sounds.Īfter digging into this issue, it seems that this is a common problem encountered by many users, not only iPhone users but also Android phones users, the problem is not more present on some type of phones than on others. It’s a strange situation which puts us in awkward positions, we’re sure we don’t press any button and the other person is also sure he/she doesn’t press any key. I even thought about the person who I talk with pressing the hard keys by mistake during the call (for old phones which have hard buttons) but all of them were using smartphones without physical buttons.
