I have been experiencing this issue for awhile now and was told by our phone support vendor that once I upgrade to 6 this should resolve the issue. Mitel 3300 software 6.0
When I go into user and device config form not all the extensions but enough of them have duplicate entries and in most cases one will be correct and the other entree will be the previous employee. I went through one day on one PBX and cleaned this all up just for it to all come back.
any suggestions would be great?
Thanks,
