Further Information
Please note the following information when using the “E.164 con-
version” feature:
z When all external lines are occupied, the “Congested” state is
only indicated later on during the dialling process.
z Emergency calls are always executed without “E.164
conversion”.
z 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.
z 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 conversion”.

connector.

conversion” in this case also.
