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

, 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 oper-

ation 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 telephone

supports this feature and the caller has activated it. What other information is dis-

played depends on the telephone. Charge display (ISDN telephones only) requires

prior configuration by your network operator.
