Cross platform VoIP that runs on i386? (Trying to call my girlfriend)

I’ve been trying to make a voice call to my girlfriend, but this has proven difficult. I’m home sick, and don’t have the charger for my standard computer here. Also, my phone recently broke.

What I do have is my trusty old laptop running Debian, so I didn’t worry as I thought I could just skype her. How wrong I was! It turns out that finding a voice call app that runs on my old i386 architecture is tricky.

On my standard computer I’d use Skype, but it turns out their app only supports 64 bit architecture. "Then you could run Skype in your browser" someone might say, but as I tried downloading Google Chrome it turns out they require 64 bits as well. I’ve tried to look at some other VoIP solutions such as Viber, but as far as I can tell they all have the same policy.

Any solution would have to be free and not to complicated to install. The girlfriend in question has a Mac, so any exclusively Linux specific software would be off the table.

Ideally, I would not like to sign up for a google account, or any other fishy surveillance deal.

Is this too much to ask for in this modern world?

Edit: I’m not necessarily looking for something to install, so if there’s something I could run in my browser that could be interesting as well!

TLDR: I’m looking for some free VoIP software that will run on an i386 architecture computer running Debian, which lets me talk to a Mac user.
