1. Call the OpenCom 100 communications system Configurator. On the intro-
ductory 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: Bundle 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 differentiation
between external and internal call numbers.

Note: For incoming calls via a bundle with the "E.164 con-
version" 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 en-
tering call numbers used for authenticating (CLIP-Auth).
