E.164 conversion 166
Telephony
Configuration
You can configure the “E.164 conversion” feature for each bundle
separately. This is possible for point-to-point configured bundles
(“system access”), for point-to-multi-point configuration (“multi-
terminal access”) and for SIP trunks:
1. Call the Forum 523/524 communications system
Configurator . On the introductory page, change the Level
option to Expert .
2. This step is optional as the country code is preallocated due to
the Country setting under System : Common .
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 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 differ-
entiation between external and internal call numbers.
