Please log in for more thread options I have a multiple line phone system. I use a head set. People start talking to me when I'm on the phone, when because they don't know if IM on the phone or not. Can someone point me to a simple circuit that I can make that would plug into the wall RJ connector and then plug my phone into to detect when I'm on the phone and light an LED to indicate I'm on the phone. I have build a few phone circuits before. But this phone is not a regular house phone, but rather a multi line "Office" phone where I'm assuming its digital or something. regards | |||||||||||||||||||||||||||||||

If you've got a multi-line system, 1) Home brew mods will void any warranty or service contract your company has on the system, and 2) I'll bet the device you want is available as an accessory, or as a different phone. Good luck Chris | |||||||||||||||||||||||||||||||

Unfortunately the manual doesn't say much about this. Yes I suppose there is something you could buy. But Being a bit of a hobbyist I was looking forward to building something. Unfortunately, I suppose there are no general diagrams for this kind of thing. Regards | |||||||||||||||||||||||||||||||

Thanks Terry for your help. I'm not advanced enough to know however which one would work on a digital line. I don't believe business phones use the same high voltages that a normal house phone uses? Interesting enough in my research I have found many people asking this same question and wanting a solution but no one with a solution. Can anyone point to ones that might work. Again I'm looking for something simple. Some of them look awfully complex. All I want is a light or something saying that someone is on the phone. right now our phones just have an liquid crystal little screen that just point to the line in use. This is impossible to see over someones shoulder or sitting accross the room. Alternatively I was thinking of putting some sort of Induction device on the hand piece that would detect a small current and then light a light. However I have not seen any schematics for this.
