Google voice callback system with selenium

Ok this is going to be a quick guide on how to implement a callback system with firefox / selenium / geckodriver
in asterisk on debian stretch
This assumes you have a running debian system with asterisk already installed
You must also have the asterisk user created
I'm not testing this, so hopefully you can debug any small holes that might arise
Usually I would re-do the whole thing on a fresh debian install, but I don't really have time atm

Go to https://github.com/mozilla/geckodriver/releases and grab either the linux32 or linux64 version
Most will probably want the 64 version
extract it to /usr/local/bin

sudo apt update
sudo apt install firefox-esr python python-pip
sudo pip install selenium

sudo bash

su asterisk
cd
Run firefox and login to voice.google.com
If any popups come up asking to save the password, do it
Now close firefox and re-open it
See if you can go to voice.google.com without it asking for password
If you can't you'll have to debug it until you can login w/o password

Now find your firefox profile directory

It's usually somewhere under the .mozilla directory in your homedir
In my case, the .mozilla directory was in /var/lib/asterisk since we're using the asterisk user
Replace the profile dir in the gvoice snippet with your profile dir

exit
You should be back at the root prompt now

Now put gvoice into /usr/local/bin
and
chmod 755 /usr/local/bin/gvoice

Now fill out the pjsip.conf and extensions.conf with your credentials and choice of passwords
Place pjsip.conf and extensions.conf into /etc/asterisk

service asterisk restart

Now make a call out of either the 201 or 301 extension

You will hear 1 or 2 rings that come from asterisk, then you'll hear the slightly different ring that comes from the google callback
and then you'll be connected

Thanks to twinclouds for the original callback system, mozilla for creating one of the first alternative open source web browsers,
python for creating an awesome language, and selenium for being able to automate web browsers!
