AT&T SB67030 Administrator's Manual page 218

Symptom
I cannot dial an outside
number. I reach an extension
instead
Voicemail is not received at
the called extension.
Round Robin extensions do
not ring in the correct order.
Incoming DID calls do not
reach my extension.
Troubleshooting
Synapse Administrator's Guide
Probable Cause
The extension prefix matches
the first digit of the outside
phone number you tried to
dial, and you don't have to
dial a digit before dialing
outside phone numbers.
Target extension Voicemail is
full.
Extension is unplugged.
Distribution List error.
The system time is not
properly configured.
Outside caller dialed the
caller ID number that came
with a fax or an outgoing
voice call was made on the
fax line. Outside calls placed
to the DID fax number go
directly to the fax machine.
Corrective Action
Change the PSTN Trunk Prefix to something other than
none. On the administrator WebUI, click System
Settings, then Dial Plan Settings.
If you want to maintain the ability to dial outside phone
numbers without a preceding digit, change the extension
prefix to avoid matching the first digits of commonly
called outside phone numbers. On the administrator
WebUI, click Extension Settings, then Basic Settings.
Select a new extension number in the Change Extension
Number to box.
Deletes messages.
Plug in the extension.
Verify the Distribution List. Log in as an individual user on
the WebUI, click Voicemail Distribution.
All devices' time settings need to be synchronized. Either
set the System Time/Date Options to automatic (if the
Internet is available) or to manual. On the administrator
WebUI, click System Information, then Basic Settings.
Set the System Time/Date Options.
Ensure that fax line uses the Pilot Number for outgoing
CID. On the administrator WebUI, click System Settings,
then Direct Inward Dial, and set the Outgoing Caller
ID for all Extension to System Pilot Number (global
setting). Then click
