13.1.3 Further Information
Please note the following information when using the “E.164 conversion” feature:
■ When all external lines are occupied, the “Congested” state is only indicated
later on during the dialling process.
■ Emergency calls are always executed without “E.164 conversion”.
■ Call number assignments in the call distribution are not evaluated for the
“E.164 conversion” feature. For an assigned MSN, e. g. no automatic internal
dial is executed even when the destination could be reached this way.
■ Depending on the telephony provider, you can possibly also use the area code
of your own country without “E.164 conversion”. Differentiating between
external and internal call numbers can only be done using the “E.164 con-
version”.
13.2 Call Forwarding
The current version of the OpenCom 100 communications system also offers con-
figuration of multi-level call forwarding. When you forward a call number that has
already been forwarded, this results in a call forwarding chain.
Call Forwarding Chain
Multiple call forwarding is executed independent of the call forwarding type. An
overview of the various call forwarding possibilities is nonetheless helpful for the
following explanations.

tional area code.
