1. Systematic Telephony
The OpenCom 100 / Aastra 800 communications system, referred to hereafter as
“the OpenCom 100 / Aastra 800”, enables the connection of standard terminals
(standard analogue telephones, ISDN telephones and cordless GAP telephones).
SMS-enabled terminals and SIP terminals can also be used. It is possible to operate
the so-called standard terminals on an Aastra 800 communications system if the
system is equipped with the corresponding telephony interface cards.
With this configuration you can telephone conveniently and use the features of
the OpenCom 100 / Aastra 800 via code-number procedures. This guide describes
how you operate your telephone in order to use the desired functions. In most
cases, you can do this by pressing the key combination
* and #, R, together
with a specific sequence of digits.
Please note the specific operating characteristics of your telephone:
On standard analogue telephones featuring pulse dialling, it is not possible to
enter data with the star key
* or hash key #.
As a result, the functionality of the OpenCom 100 / Aastra 800 features is only
available to you on a limited basis. It is thus better to use telephones equipped
with dual-tone multi-frequency (DTMF) dialling. Modern telephones often allow
you to switch between the two dialling modes.
When telephoning via SIP (i. e. telephoning via the Internet Protocol “Session Initi-
ation Protocol”) entry of the hash key
# is only permitted at the end of a code-
number procedure or of a call number. You can thus only use a part of the code-
number procedures on a SIP terminal. Furthermore, some SIP terminals offer
operation of features at the mere press of a button. Please review the user guide of
the manufacturer.
In the case of ISDN telephones, certain features can be operated via menus or
function keys. Refer to the operating instructions of these telephones for details.
On telephones with a display, you can read the caller’s call number if the tele-
phone supports this feature and the caller has activated it. What other information
is displayed depends on the telephone. Charge display (ISDN telephones only)
requires prior configuration by your network operator.
