If Error tone is returned to you after dialling the line access code then your extension is call
barred.
Barred Calls
– You will not be able to make calls for which your extension is call barred. If
you try and make a call to a barred number, error tone will be returned to you.
Internal call - Internal dialling is not possible on telephones for which spontaneous outside
line seizure with internal is set and which do not have a
R
key (hash key) or which do not
support this key.
DTMF signalling
- It is possible to send DTMF Tones during a call. This can also be done
during an enquiry call, Brokers Call and Three Party Conference. Any digit from 0 – 9
including * and # can be transmitted.
An outside line which has been reserved will only ring your extension for 60 seconds
after which the call back for the outside line will be cancelled.
If an error tone is returned when booking a reservation for an outside line, then this means
that the line has already been reserved by another extension.
You may dial 99 on telephones which do not have a
S
button.
