Change destination for all extensions (via CLI)

Hi,

is there a way to change the destination for all extensions from the Voicemail to a specific ring group?

It would be nice, if it’s possible via CLI, because the GUI does not work yet, as I’ve already reported here: http://issues.freepbx.org/browse/FREEPBX-11475

I need to change this as soon as possible.

Hope, somebody can help me.

Thanks,
Sebastian
