Troubleshooting
Synapse Installation Guide
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.
DID numbers do not change
when extension numbers are
changed.
There may be a DID range
error or the DID has been
used.
The browser is not checking
for newer version of pages.
Corrective Action
Change the extension number again. Make sure no one is

using that extension while you are changing its settings.
a. Log in to the WebUI as administrator, click
Extension Settings, then Basic Settings.
b. Enter a new extension number in the range 100–999
into the Change Extension Number to box.
Assign a DID number to the extension.

a. Log in to the WebUI as administrator and click
Extension Settings, then Basic Settings.
b. Select a DID number from the Select DID drop-down
list.
The DID is not within the DID ranges configured or the DID

has been already assigned to another Deskset. Check the
DID ranges configuration.
a. Log in to the WebUI as administrator, click
System Settings, then Direct Inward Dial.
b. Verify the Current DID Ranges.
Ensure that your Internet browser is working normally. It

may not be automatically caching pages. For example, in
Internet Explorer 7, click Tools –> Internet Options. Then
under Browsing history, click Settings. Under Check for
newer versions of stored pages, select Automatically.
