Outgoing Calls - AT&T SB67030 User Manual

Outgoing Calls

Symptom
I cannot dial an outside
number. I reach an extension
instead.
Unable to make outside calls.
Troubleshooting
Synapse SB67030 and Accessories User'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.
An outside phone number
cannot be accessed through
the Gateway.
Corrective Action
Change the PSTN Trunk Prefix to something other than

none. Log into the WebUI as administrator, 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.
a. Log into the WebUI as administrator, click
Extension Settings, then Basic Settings.
b. Enter a new extension number in the range 100–999
or 1000–9999 into the Change Extension
Number to box.
Ensure that you enter a 9 or whatever digit, if any, that

must be dialed first for an outside call. For example,
9-1-555-0123.
If you see All Phone Lines Busy on the Deskset screen,

try again later because all outside lines may be in use.
Ensure that a Gateway is connected to the network and

that it resides on the same subnet as the Deskset.
