3CX Web API / 3CX Phone System Web API

Fork from Montesuma80/3cx-web-API with updates for use with 3CX v20 Update 2.
This is untested and I cannot guarantee it will work or be secure.
Use at your own risk and strictly limit access to the API.

Run as systemd service (Linux)

If you want to run it as an systemd service you can use this example service file to create your own systemd unit. The api listens on port 8888. The access to this port should be strictyl firewalled and only allowed from the 3CX server itself. For accessing the API from outside the server, you should use a reverse proxy with authentication.
