An extension number was not changed correctly.
Probable Cause
That extension may have
been on a call while the
extension number was
changed in the WebUI, or
someone tried to change the
extension number to a
number that was already
being used.
I changed an extension number, but the DID number did not change.
Probable Cause
DID numbers do not change
when extension numbers are
changed.
I cannot find the specific DID number for assignment on the DID Assignments page.
Probable Cause
There may be a DID range
error. The DID is not within
the DID ranges configured.
WebUI reverts to Log-in page after clicking a navigation link.
Probable Cause
The browser is not checking
for newer versions of pages.
