Analogue and
ISDN-Phones
When making an external enquiry / brokering you must always seize the outside line by
pressing „0“, even if spontaneous outside line seizure with internal is set on the telephone.
An outside caller will hear Music on Hold if placed on hold.
If you replace the receiver during an enquiry:
- You clear the current call,
- You receive a callback if a call is still on hold,
- You transfer an external call on hold to the internal user with whom you were in an
enquiry.
Connection charges are incurred for the external call, even while the call is on hold.
Notes
Automatic Call Back
You can set up an automatic call back if the number you are calling is busy. This feature is
only available to subscribers of ISDN lines. Your phone will ring as soon as the called party
replaces the receiver. The other party will be called automatically as soon as you pick up your
receiver.
If you hear the error tone then it will not be possible to be called back from the busy number.
The feature Call Back on busy is not available from the telephone exchange.
The feature will be cancelled if you do not answer the returned call within 20 seconds.
Call Back will be cancelled if the Call Back feature is completed or failed to connect the call
after 45 minutes.
