Live-generate configurations for your Polycom handsets via a MySQL database.
To deploy, retrieve a copy of sip.ld from Polycom's website (too large to include in the repo)
Now, install schema.sql into your database server, then use PM2 (npm install -g pm2) to start ecosystem.json after editing its database and server fields.
Now, add your user's phones into the database and have them pull new data.
I've used data from Polycom's website in their example configuration files. These are provided openly on their website and seem to have no license attached. If this is determined to be a problem, please contact me.
