Zones

A zone represents a list of phone numbers which can be called for a certain tariff. You can assign a provider to every zone accoring to date and time.

Zone name
Enter a name for for the zone, e.g. longis distance or mobile.

Area code list
All phone numbers which start with digits provided in the list belong to this zone. The phone numbers are compared during processing the Dialing rules. The phone numbers must be entered in the super canonical format (e.g. "+1171").

Examples:

Area code	Meaning
+1	All numbers which begin with +49, in other words all phone numbers in Germany (apart from special numbers).
+1905	All phone numbers which begin with +1905, in other words all numbers in Toronto, Canada.
+117	All phone numbers which begin with +4917, in other words all mobile phone numbers in Germany with a 017x dialing code.

Instructions
You typically configure zones for local calls, long-distance calls and mobile phone networks and several zones for other countries.

Priority of longer dialing codes
If there are several dialing codes configured in different zones which fit the phone number, the zone which has the greater number of digits in its dialing code is used.
Example: the number +4917123456789 is dialed. If +4917 is entered in zone 1 and +49171 in zone 2, zone 2 is used because more digits match.

Priority of zones without providers
If there are several dialing codes configured in different zones which are identical and one zone has no provider assigned to it the zone without a provider has priority.
