Hi everyone, I have a project in mind but I would like to understand first if it is possible to do it and which components I need.
I have the following modem: Manual
The back of the modem is composed as follows:
What I would like to do, whenever I get an incoming call, intercept that call and via arduino send a message which can be a push notification to an android device or something on Discord or Telegram that someone is calling.
Do you think it's possible?

Do you want to keep the one in the English section or the one in the Italian section? we will close the other one.
Post deleted, if there are things to edit in the message let me know in detail if you can't edit it yourself.
Do you expect to capture and pass on any information from that call, or just register the fact that a call was received?
Original idea is to know that I am receiving a call and the number of the caller.
What other kind of information can I have, what were you thinking?
Well I was thinking, "almost none" without some special equipment. Ring detection is relatively easy. Caller ID is some kind of tone encoding, I forget how it works (because most desk phones are gone now). Have you done any internet research on this?
thanks. appreciated.
Your short url does not work. is this VoIP ?
do you expect to have the phone as well (ie some sort of pass-through)?
On another point, "intercept" can mean that the call is blocked from the phone. Is that the case?
The calls go through the modem, I was thinking of connecting the arduino with the modem through the telephone port which is in the modem in line 2, as seen from the image.
No.
No, Simply A is calling me, as soon as the phone rings at the same time I should receive this information or the arduino process this information that someone with the following number is calling.
If I haven't explained myself well, I'll give an example.
may be this would be of interest
Do you currently have active, working calling number display on the phones?
Yep.
I can't find an English version of the manual which describes this TIM DSL modem/router.
If the signal at the outlets Tel1 and Tel2 is analogue (i.e. you can plug an old phone into it and it will work) and all you want is a notification, via the internet, that a call attempt has been made to the number assigned to Tel1/Tel2, then you could base a project on that described in post #10. However, that is not a beginner's project.
If, however, the Tel1/Tel2 outlets are intended for VOIP (SIP endpoints), the described project is not relevant. I haven't seen any Arduino projects where SIP traffic is decoded but, provided it is not encrypted, it would surely be possible.
What components do I need exactly in case?
Version of arduino, wifi card and more.
In principle, it uses an ESP8266. Because that has a poor ADC, I used an external SPI connected ADC. If I was doing the project again, there are some things I would change. For example, the ring detection currently detects the ring frequency in the voice channel and I would change that to detect the ring voltage instead. However, as I said, this in not a beginners project. You'd have to look at the schematic and build your own bill of materials. You should also build/test in incrementally. For example, build and test the notification parts and the demodulator parts separately as mini-standalone projects and put it all together at the end.
