Symptom
Unable to make outside calls.
I cannot make international
long distance calls.
I cannot access phone
company services like 411.
Troubleshooting
Synapse User's Guide
Probable Cause
An outside phone number
cannot be accessed through
the Gateway.
If no trunk prefix (digit
entered before dialing
outside calls) is set, phone
numbers, including
international or country
codes, that start with 0 (zero)
will go to the Synapse
system operator.
If the PSTN Trunk Prefix is
set to none and any x11
extensions already exist
(such as 411, or 611), then
the extensions takes
precedence. In other words,
dialing 411 calls extension
411, not the 411 directory
service. 911 cannot be
assigned as an extension
number.
Corrective Action
Ensure that you enter a 9 or whatever digit, if any, that
must be dialed first to indicate this is 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.
Set the trunk prefix to something other than none. On the
administrator WebUI, click Dial Plan Settings, and then
select a digit from the PSTN Trunk Prefix from the drop-
down list.
Ask the system administrator to change the extension
number.
Ensure that you enter a 9 or whatever digit, if any, that
must be dialed first to indicate this is an outside call. For
example, 9-1-555-0123.
