Outgoing Calls
No dial tone.
When you dial an external number, you reach an extension instead.
You cannot make calls to an external number.
Probable Cause
Corrective Action
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.
Probable Cause
Corrective Action
The extension prefix matches
the first digit of the external
phone number you tried to
dial, and you don't have to
dial a digit before dialing
external phone numbers.
Consult your system administrator.
Probable Cause
Corrective Action
An external phone number
cannot be accessed through
the Gateway.
Ensure that you enter a
9
or whatever digit, if any,
that must be dialed first for an external call. For
example,
9-1-555-0123
.
If you see
All Phone Lines Busy
on the Deskset
screen, try again later because all external 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.
Call Appearance mode
only —
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.
