E.164 conversion
146 Telephony
Call the Telephony : Settings page. Click on the Change button. Enter the
country code without a zero in front into the International area code field,
e. g. “49” for Germany. The setting in the Own area code field is not
relevant for the “E.164 conversion” feature. Confirm with the Apply
button.
3. Call the Telephony : Trunks : Trunk group page or the Telephony : Trunks :
SIP trunks page. Click on the desired bundle or desired SIP trunk. Activate
the E.164 conversion option.
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 Apply button.
4. Call up the Telephony : Trunks : 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 bundle used for networking communications systems cannot be
used with the “E.164 conversion” feature. Please keep in mind that the differ-
entiation 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 auto-
matic 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).
