MW XXX keys, anyone recall what SW version Samsung started supporting this feature?

It had to be really recent, I just noticed it worked a couple of weeks ago with a bunch of 7400's and a central 20i.
Customer was previously on 4.7 and it did not work.

Yeah, I agree had to be recent, just can't find anything in the release notes about it.

I've got all release notes they've put out since 4.5 and i'm not seeing any reference to it.

As far as I was aware it didn't work.
Must be 4.8 or 4.9

Great if it works, saves me having to create list mailboxes

Working on two new 7200's connected via a VPN with SPNET. Programming would let me program an MW key for a remote mailbox, but it would not save it. If you went back and looked at it, it just saved it as a blank MW key. Any ideas??
