The answer to your question is "no".

Everyone dismisses me.
I know these phones are bugged, I just can't prove it.

Would you please tell us the make and model of the telephones? Also, if you have the schematic of the phone or PCB that might help as well.

The make and model is the Kingtel KT-9290.
I don't have a schematic of the PCB but I did link pictures to the actual circuit board.

The three ICs on the PCB are
UTC31002
UTC1062
HM91710AP

 

I've already been threatened by them because they suspect I know something.

If you've been dismantling their phones is it any wonder?
Tape a bit of felt over the phone's mic when not in use . If it gets removed by someone other than you then you might have grounds for suspecting a bug.

 

To be clear, the answer to your question " Can the ringer circuit on this telephone together with the piezoelectric ringer be used to transmit room audio via RF?" the answer is "No."

 

I've already been threatened by them because they suspect I know something.

Or, rather, they're tired of your accusations and you not doing your work.

 

And you are going to get yourself fired for tampering with the office equipment.

You come off as borderline schizophrenic. Get some help.

 

Can anyone tell me what these are?
I've asked a few people and they have no idea. We're not engineers

Don't know. It's hard to tell without some context. Where did you encounter these? Whatever they are, the fact that they are encased in transparent plastic would suggest they might be some kind of light (or IR) sensors or emitters...

Don't feed her paranoia. They are splice connectors.

 

They're ordinary telecom IDC wire connectors.

 

I post the following in the spirit of fun. Erica, please don't take too much offense -- this is just what comes to mind when I read your posts:

 

Don't feed her paranoia.

Hey, at least I didn't say they look like ultra-miniature microphones...

 

I think they are some kind of antenna for the RF emitted by my phone.

 

You shouldn't be afraid of bugs at work unless you're doing something you're not supposed to do.....

How do you know there is any emitted RF? What characteristics (frequency, modulation) does it have?

I have no idea.
But I have a IC-R20 communications receiver 150kHz to 2.2 GHz I'll search the spectrum on AM and FM.
Spectrum analysers are so costly.

Is there any easy way to determine if RF is emitted from the phone? RF comes off as photons?

I know that the phone is bugged. I know.
The audio is not leaving via the telephone line - I checked with an oscilloscope. It must be coming off RF and the piezo ringer polarity is the only modification on the phone.

Perhaps the bad bios article is not bogus.

 

I know that the phone is bugged. I know.

How, exactly, do you "know" the phone is bugged? Keep in mind that merely suspecting the phone is bugged is NOT the same as knowing the phone is bugged-- no matter how intense your suspicions.

Be explicit: how do you know the phone is bugged?

Because I've been threatened by these people. They know I suspect the telephones but I can't prove audio is leaving.

 

Perhaps they also swopped the ICs and relabeled them to appear unmodified.

 

Because I've been threatened by these people.

What sort of threats? And why?

 

RF comes off as photons?

Eh? Photons = light. Can you see it being emitted? Does your phone glow in the dark?
