Extensions cannot make external calls
but incoming calls and internal calls
are OK
This could be due to:
Base station may have Call Barring set
to stop outgoing calls. Up to three user
programmable ‘emergency’ numbers can
be set on the system. (
999
and
112
emergency service numbers cannot be
barred).
Extensions cannot make or receive
any external calls but internal calls
are OK
This could be due to either of the
following:
• External lines may not be connected.
• Call Barring may have been set to stop
all calls except internal calls, see your
System Set-Up Guide.
Can sometimes dial an internal
number but get the wrong person
This could be due to any of the
following:
• Users may have got their extensions
mixed up. Check that each user’s
extension is on the correct internal
number.
• Your extension or the extension you
are calling may be registered with
more than one base and is logged on
to the wrong one. Please check that
you are both registered to the same
base.
Extension does not ring with any call,
internal or external
This could be due to any of the
following:
• The extension ringer volume may be
set too low or switched off. To adjust
the ringer volume at the handset, see
your Handset user guide. To adjust the
ringer volume at an attached telephone,
see you telephone user guide.
No dial tone
• Check that the Diverse ISDN is
plugged into the ISDN socket.
This would affect all handsets and
telephones.
Handset does not ring with external
calls but rings with internal calls.
This could be due to any of the
following:
• The extension may not be included
in the call group for the external
phone numbers, see Call Allocation
in your System Set-Up Guide.
• The handset may have been set to
for ward calls without ringing, see
Call Forwarding on page 20, 21
(Executive Handset), or page 34, 35
(Additional Handset).
Cannot set Call Forward from an
extension
This could be due to:
• The destination handset or telephone
already has Call Forwarding set on it.
It is only possible to forward a call to
one destination.
