Telephone Tones & Ringing
Various tones and ringing are used to indicate calls and other events.
Incoming Calls
:
• Repeated Double Ring: External call.
• Repeated Single Ring: Internal call.
During Calls:
• Repeated Single Pip: Another extension is about to intrude
or has intruded on your call.
Outgoing Calls
:
• Continuous Tone: Number called is unobtainable or
set to no calls. Phone locked, no
external calls (or phone is barred).
• Repeated Tone: Busy number.
• Dial Tone: Dial number.
• Repeated Single Pip: Phone on divert or no calls.
Night Service
The system can take different areas into and out of night service automatically. It
does this following timetables setup by the System Manager. The effects of night
service vary, but typically they are as follows:
• Lines: The system directs calls to a night desk number or answer phone
extension.
• Phones: The type of calls you can make becomes more restricted, eg. no
international or long distance calls.
Dialling Timeout
After you start dialling, if you do not dial another digit for several seconds the system
assumes that you have finished dialling. The system then ignores any further digits
that you dial. By default the timeout is 5 seconds though this can be altered.
Since it is your phone that generates the audible dialling tones, the system's dialling
timeout does not affect calls connected through the system to services that need to
hear additional MF tones (e.g. voice mail systems, BT star services, etc).
Feature Passcode
The requirement to enter your passcode for many of the phone's functions, indicated
by a double-tone, can be switched off by the System Manager. If this is the case
then, for non-voice mail functions you can ignore instructions to enter your
passcode.
Call Waiting
If, whilst you are engaged on a call, another extension rings your number, you are
notified by a single tone burst that is repeated every 30 seconds. Only you will hear
this tone burst. You can Hold the existing call and answer the waiting call, see page
14 for detials.
