Outgoing Calls - AT&T SB67020 User Manual

Outgoing Calls

Symptom
No dial tone.
When you dial an outside
number, you reach an
extension instead.
You cannot make calls to an
outside number.
Troubleshooting
Synapse SB67020 Deskset User's Guide
Probable Cause
Handset cord is plugged into the
wrong jack.
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.
Your extension has a trunk
reservation for outgoing calls, and
all lines and channels are being
used for active or incoming calls, or
are reserved for other extensions.
Corrective Action
Ensure the handset cord is plugged into the handset

jack on the side of the Deskset. Do not connect the
handset cord to the corded headset jack on the back
of the Deskset.
Consult your system administrator.

Call Appearance mode only—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.
Wait for a channel or line to become available.

The system administrator can either remove the

reservations from some trunks or contact the service
provider to add more analog telephone lines or T1
channels.
