Strange noises on telephone

Hi everyone,

My brother was looking for his cellphone today, so he used the home phone to call the cell. When he found the cellphone, he pressed the hang up button on the cell. This is when the strange sound occurred on the home phone. Sounds like a totally messed up frequency or some Morse talk. And about every 5 seconds it sounded like a voice hidden in the distorted frequency. But maybe I’m wrong.
Can anyone tell me what it could be and if there is a way to clear it up?

Thanks in advance,
Morgy

Sounds like a crude computer-synthesised-voice glitching , e.g. …

The last three words sound like “thermometer” “computed” “horizon” , so maybe telemetry.

How did you capture the Home Phone audio? If you like to use an inexpensive “Phone Recorder,” that can upset the balance of the phone line and make it susceptible to cellphone radiation. That happens to a microphone recorder I have and one speaker system. I can hear the cellphone negotiating a connection and periodically issuing the “Keep Alive” signaling.

I’ve never had it happen to a well-shielded professional XLR microphone. Always the less expensive equipment.

Hey,

So I never recorded it digitally. No. I just took a video of it with my Samsung phone and converted the video to mp3.

I am so totally lost. You said the cellphone hung up and the noise occurred on your home phone, I assume “telephone or land-line.”

I’ve changed my mind about the last phrase : sounds more like “spotters up” …

But the last phrase is in a different accent to the other words, an accent like my own, so my new interpretation may be pareidolia.

Yeah, my brother searched for cellphone so he rang it from the home phone (land-line).
His cellphone actually rang, so he found it and hung up the cellphone.
Then, the home phone immediately started making these noises, so after two minutes of it making noises, we decided to record it with the cellphone (took a video of it and converted it to mp3)

And to everyone else, thanks a lot for posting your thoughts etc.
I’m not sure if you could be these words. In fact, we in Germany, so maybe it was something in German?
Either way, it sure does sound like those English words!! Creepy.

Not sure about the cause, because it happened after he hung up his cellphone. Maybe it really could’ve been a “Keepalive” signal? Because the home phone “thought” the connection to the cellphone broke down?

What do you think…?

Sorry for having to reply again. Forgot to mention that the home phone is a land-line, but it’s connected to our WiFi router. So it goes through the router.
Maybe these noises had something to do with the router? Any possibilities?

Curiously there was an article on BBC Radio 4 (You and Yours) today about just such “interference” on a land-line phone. This was die to villains hi-jacking the landline and diverting it to their cellphone - in that instance to try to gain access to the victim’s bank account - so be wary.

Forgot to mention that the home phone is a land-line, but it’s connected to our WiFi router. So it goes through the router.

So it’s not a POTS Land-Line telephone like the Public Switched Telephone System. It’s a VOIP phone like Vonage.

So once the call is established but not completed, the phone is going to receive whatever happens when half the connection goes down. If that’s an unsupported condition, then goodness knows what you’re listening to. It could be your VOIP manager searching for an active connection.

“Nope, not that one. Nope, not that one either…”

It is certainly not German.

Sounds English to me as well - not least because of the “…uted” sound.
There are not much German expressions that would sound like that.
For instance: “Er hat sich gesputet” - he hurried - very rare.

Sounds like VOIP retraining. It shouldn’t land on the phoneline’s audio, but lots of these DSL voice routers are a bit buggy.

I don’t hear words, just test signals from a DSL figuring out how much audio bandwidth and latency there is. And that sounds oddly human in a cartoon-like way sometimes :sunglasses:

Does it explode if you use your VOIP phone to call the copper/48v land-line phone hosting the DSL?

If you survive the detonation, that will tell you what your delay is.
