Once upgraded to Embedded VM 4.0, is there any going back to 3.2? I want to downgrade, because with 4.0 I cannot set night/oos groups by utilizing the traditional method whereby I have groups with single users who are set to forward unconditional to a short code that points to an AA.
Or, will a 3.2.55 system work with an embedded card that has been upgraded to 4.0?
