2.1 Seizing an External Line
If your telephone is set to manual line seizure, all call keys on your telephone first
seize an internal line, and you can dial an internal number straight away. When
making external calls, you must first press the line seizure code digit
(presetting:
0).
Note: This also applies to all enquiry calls and call forward-
ing to external destinations, but not to call forwarding
“MSN”.
Your system administrator configures this code digit for all subscribers on the
OpenCom 100 system and will tell you what value is currently valid.
If your telephone is set to automatic line seizure, all call keys on your telephone
seize an external line, and you can dial external numbers straight away. In order to
reach internal subscribers, press the star key twice
* * before dialling the
internal number.
Note: This also applies to the destination numbers you spec-
ify when configuring call forwarding or a baby call.
