DECT dropping registrations on a merge

[t3rm3y]

We have a site which was originally on an early 10.0.

​

x release of dect, but if we sent a merge on the manager the handsets would lose registration.
We solved it by downgrading the dect base stations to 7.2.28 i think to solve issue but limited the number of base stations we could use,
I see that 10.2.9 is released and seems to have resolved the issues.
Anyone upgraded to test?
Would upgrading retain the registrations as it is a school and has about 50 handsets so we dont really want them dropping off.

Check the DECT users mailboxes, I have known handsets to lose registration if they have a lot of unread voicemail messages.

If you put a large switch in some cave somewhere, with a sign on it saying 'End-of-the-World Switch. PLEASE DO NOT TOUCH'.
The paint wouldn't even have time to dry.”
