AT&T SB67010 Gateway, SB67030 Deskset System Administrator’s Guide
Cannot make external calls.
An external line cannot be
accessed through the Gateway.
Ensure that you enter a
9
before the telephone
number to indicate this is an external call. For
example, 9-1-555-0123.
Ensure that a Gateway is connected to the network
and that it resides on the same subnet as the
Deskset.
If you see “All Phone Lines Busy” on the Deskset
screen, then try again later because all external lines
may be in use.
Deskset does not receive
incoming calls.
Incoming call notifications have
been suppressed or are unable
to reach the Deskset.
Ensure that the Ethernet cable is securely plugged
into the network port beneath your Deskset and that
the other end is plugged into your office LAN.
Ensure that Do Not Disturb (DND) is not on.
Ensure that Call Forward All (FWD ON) is not on.
If the Deskset does not ring on an incoming call,
press the
VOL+
key to increase ringer volume.
Incoming calls may be directed to a Ring Group that
you are not part of.
Excessive echo heard at the
Deskset on external calls.
The automatic line calibration did
not run properly.
There may be non-system equipment connected in
parallel to the telephone line.
