Export is fine. However when I delete all the duplicates and click ok to save changes it gives me this error An item with the same key has already been added. Key: 0 .
So I can't update the DB by deleting all duplicates. Everything what I do, ends up with this error.
I wonder if you are able to use the rest of the pbx features, like adding users, editing them, adding sip trunks, inbound rules, overall is everything ok? or do you have the same issue too?
is the pbx running version 18.0.8.917?
did you try clicking on the Cleanup button within the call cost menu?
