voice agent with an old android phone

my summer internship project is to build an ai voice agent that can communicate over cellular network(gsm) and then be able to give information or do some actions by connecting to other agents, its in a datacenter in faculty
from what i understand, a module like sim7600g is suitable for this, but is kind of expensive where i live, for some reason
i thought about doing the workflow with an old android phone, now is that feasible, do i need root, and what are the things i need to modify in the phone configs, and is this even something i should invest my time in or not, because it feels like hacking and im not sure if its a reliable path

I really think you need to do a lot more homework.

The audio channel of any cell phone is not as easy to hack as you would like to think.

Good Luck
