Docker container for demoing Wi-Fi calling stack.
docker-compose build
docker-compose up
Point RedirectVoWiFiTweak to your computer's IP address.
Install it on a jailbroken phone, enable Wi-Fi calling, and you should see a VPN connection into the container.
There's a ssh daemon on port 22222 for debugging: the password is
root:vowifi. It's useful for using sshdump from Wireshark.
baresip, a popular command line SIP VoIP app, is also preinstalled. If you ssh in, you can run:
ssh -p 22222 root@localhost
baresip
/uanew sip:+15554443333@localhost
/dial sip:+19085823275@localhost
to ring your connected phone (replace +1 908-582-3275 with its number).
be careful! do not expose the ssh daemon or the VPN to untrusted devices.
Currently the Kamailio config is set up for a Verizon SIM, with domain set to
vzims.com.
For other providers, capture a SIP REGISTER from the phone (using rvictl on a Mac), look at the domain, and edit app/kamailio-local.cfg.
