SIP Telephony
Telephony Technical Specification:
We create an apk file and upload it to an Android phone with a SIM card
We grant all necessary permissions
Next, we need to connect to this phone via a web panel, as a dialer
We should be able to call from the phone where the apk application was previously installed - to any number
The sound should be transmitted from our side (the caller from the web panel), microphone, speaker
And from the side of the person being called
This can be implemented as a connection through a SIP account. And call with Zoiper conditionally
The main task is to make calls from the SIM card that is in the phone - remotely, without being near the phone
Regarding permissions, special capabilities and admin rights are allowed. But without root access
Propose the price and deadlines

3232 37 3 Good night!
I am interested in your project. I already have an understanding of how to implement it and the necessary experience for this.
For remote call management, I would suggest an architecture based on SIP and WebRTC. This is a reliable and proven approach that will ensure real-time audio transmission between the web panel and the phone.
An APK with a SIP client (for example, based on PJSIP) will run on the Android device - it will receive commands from the web panel via WebSocket and make calls through a physical SIM card. Audio from the microphone and to the speaker will be transmitted via RTP streams, streamed through a media server (Asterisk/FreeSWITCH).
On the web interface side, management and audio communication will be organized through WebRTC - the user will be able to speak directly from the browser, and the audio will be directed to the phone and the interlocutor.
… The price and deadlines are still conditional - after clarifying the details, I will be able to provide an accurate estimate.
Overall, I already understand the technology stack, and the implementation is quite possible. There are a few nuances, but I have worked with something similar before and know how to solve them.
Feel free to reach out, and we can discuss the details! I will be happy to help.

это решение технически очень трудно реализовать, писал подобную вещь 1.5года(пока не закончилось финансирование), завершили на передаче звука через usb, но из-за интерференции оно стабильно не отрабатывает
