Volume fix for magicJack plus with router
Update 2013-11-08: Originally, I thought this volume fix worked. After hearing back from Kher and Bill (commenters below), I performed multiple tests on both the magicJack 2012 and 2014, I find that settings revert back to what seem to be fixed settings for the telephone volume controls when plugged into the router. There is no way to adjust volume settings while the device is connected directly to the router. This is a real problem that magicJack needs to address. There needs to be a way to directly change volume settings while connected to the router. The only way this is likely to happen is if the device hosts a device web interface. Hopefully it will be addressed in some future version of the software.
