Area Code
Area codes are also known as Numbering Plan Areas (NPAs). They usually indicate geographical
areas in a country. This feature is necessary when dialing a phone number outside the code area.
For example, an area code is configured as "Code: 0592, Min Length: 1, Max Length: 15". When
you dial out the number "56789" (the length of the number is between 1 and 15), the phone will
add the area code and dial out the number "059256789". You can only configure one area code
rule on your phone.
To configure the area code via web user interface:
1. Click on Settings->Dial Plan->Area Code.
2. Enter the desired values in the Code, Min Length (1-15) and Max Length (1-15) fields.
3. Enter the desired line ID in the Account field or leave it blank.
Time out for dial now rule is configurable via web user interface only.
