Outgoing Calls
Symptom Probable Cause Corrective Action Outgoing Calls
No dial tone. Handset cord is plugged into the
wrong jack.
 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.
When you dial an outside
number, you reach an
extension instead.
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.
 Consult your system administrator.
You cannot make calls to an
outside number.
An outside phone number cannot
be accessed through the Gateway.
 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.
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.
 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.
