Special Calls
27
are available and with which code-number procedure these can be forwarded
depends on the entrance intercom that is connected.
All entrance intercom calls are terminated automatically after a certain length of
time has elapsed. This ensures that the forwarding of entrance intercom calls does
not unintentionally result in a permanent connection (e.g. to a mailbox).
The length of time can be set by your system administrator to a value between 30
and 300 seconds in the OpenCom 100. Please ask him for the current value.
No call forwarding can be set up for doorbells on a SIP terminal.
7.9 Keypad Dialling
H*12 Z (keypad code digits)
For consultation calls:
GR*12 Z (keypad code digits)
Certain European network operators require the keypad protocol to be used in
order for you to be able to set certain features (this is not the case in Germany).
You use the sequence
*12 to switch to the keypad protocol, and subse-
quently enter the code digits required by your network operator. These are trans-
mitted directly to the exchange and evaluated there.
You will then generally hear an announcement as confirmation.
