E.164 conversion
242 Telephony
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 indi-
cated 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 phone number, e. g. no auto-
matic 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 conversion”.
Number handling with E.164 and lists – black list, white list, etc.
The combination of E.164 numbering scheme and black-, white, special lists
requires explicit duplex/triplex handling of numbers in all eventually possible
formats.
Example: 0-6104-1234, 0-030-6104-1234, 0-0049 30-6104-1234.
All these possible formats can be dialled and so work around the e.g. black
list. That has to be considered in programming these features.
0024444888
(Internal) 888
The local area code and the access call
number are deleted. The destination is
called internally without using the ISDN
connector / SIP trunk.
+3224444888 888
You can only enter the plus sign (after
E.123) with a SIP telephone (see
Internal
SIP Subscribers starting on page 166).
There is a “E.164 conversion” in this case
also.
