Is the OPEN Networks 812L sold by Internode a locked unit?
No – the “factory default” configuration of the 812L has been customised to work with NodePhone, however any and all settings can be modified if you so choose. Naturally, if you modify the configuration, you may create results that are unexpected and Internode is not responsible for changes you make to your configuration. Further configuration information for the OPEN Networks 812L is available here.
