The following setting is only relevant if the local area code is not part of
the ISDN-MSN (Germany and Austria) in your national ISDN. If you have
selected “Germany” or “Austria” under
System
:
Common
as the
Country
setting, you also have to enter the local area code into the
Area code
field
for the bundle. The prefixed zero is not necessary.
Confirm with the

Call up the
Telephony
:

:
Route
page. Check whether the
Type
setting for the used routes is set to “Private” or “Business”. For routes of
the type “Internal” the “E.164 conversion” is not active.
The Q.SIG-IP bundle used for networking communications systems cannot be
used with the “E.164 conversion” feature. Please keep in mind that the
differentiation between access call number and extension only takes place
with system access or DDI-capable SIP trunks and also only when using direct
extensions. With a call number allocated via call distribution there is no
automatic differentiation between external and internal call numbers.
Note:
For incoming calls via a bundle with the “E.164 conversion”
feature each external call number (“CLIP”) appears converted
into the international format and is also saved in this format e. g.
in the caller list. Keep this in mind when entering call numbers
used for authenticating (CLIP-Auth).
