In the ISDN Zone the area code should be stored as just 8, since Cisco TMS will add a 0 in front of it
when dialing between Swedish area codes, and add +46 when dialing from outside Sweden.
There are some exceptions to these rules, but Cisco TMS is aware of these exceptions.
Some countries like Norway do not use area codes; the area code field in the ISDN zones in
these countries should therefore be left empty. An example of a valid number is +47 12345678.
Some other countries like Italy include the leading zero in the area code even when being dialed
into from outside the country. This means that the area codes in the Italian ISDN zones should
include the leading zero. An example of a valid number is +39 02 12345678.
Other countries again such as Switzerland include the area code with the leading zero when
dialing within an area code and when dialing within the country, but remove the leading zero when
being dialed into from outside the country. Cisco TMS knows this, so the area code for ISDN
zones in Switzerland should only include the area code without the leading zero. For example:
+41 33 1234567 and 033 1234567.
Area code rules
Area code rules are typically used in the US to set up 10-digit dialing and area code overlays. Area
code rules determine how ISDN numbers are dialed from one area code (the area code set for the
location) to other area codes.
To add or edit an area code rule for a location, click Area Code Rules inside the ISDN zone. After
clicking the link, a page with an overview of all area code rules for the ISDN zone is displayed.
New rules can be added to the location from this page by clicking New Rule.
You can edit old rules for the location by clicking the Edit links to the right of every rule.
To delete a rule, select it and click Delete.
Note: In a US phone number, for e1 (123) 456-7890, the area code consists of the digits in
brackets (123), and the prefix consists of the digits 456 (in this example).
Create a new dialing code for the selected location by clicking New Rule.
When adding a new rule for a location, fill in the fields as described below.
When dialing from this area code to the
following area code (Field 1)
This field, combined with the prefix field explained
below, decides the area code that this rule applies to. It
may be set to be the same area code used for the
location.
With the following prefixes (Field 2)
The rule will only apply to the calls made to the area
code in Field 1, with the prefixes listed here. If this field
is left empty, the rule will apply for all calls made to the
area code in Field 1.
Include Area Code
If checked, the area code in Field 1 will be included in
the call. If unchecked, the area code will not be included
in the call. For the US, select this check box to enable
10-digit dialing.
Before dialing, also dial
If the rule applies, as stated in Field 1 and Field 2, the
digit(s) in this field will be dialed first when making a call.
In most cases this field will be empty.
Click Save when you are done defining your new area code for this ISDN zone.
Note: When an Area Code rule is used, prefixes from the ISDN zone are still used, but domestic
dialing behaviors (such as inserting a 1) are ignored by Cisco TMS.
