Thank you, that was great info, however your website needs to be fixed, it showed up in Euro for me, however it did charge me Canadian... I do have another question... I find when there is an incoming call, the "ringing" isn't loud enough... it isn't on par with other system sounds on my Surface Pro 4 on Windows 10 Spring Creator's Update build 1803... please show me how to fix that... in system tray, sound mixer, Zoiper isn't even an option.
