database.registerUnknown.regex pattern for IMEI validation
You cannot really fully validate IMEI using a regex. The best you can do is just check that it's 15 digits.

I need to enable database.registerUnknown , so that devices register on server automatically.
but I also need to enable database.registerUnknown.regex to validate only valid IMEI on the server to prevent registering unknown TCP connections.
so could anyone help for proper regex for valid IMEI?
