Call Restriction

Simple call barring can be applied using short codes. This uses the fact that the IP Office checks dialed numbers for short code matches in a specific order, see Matching Order.

Example:
We want to allow only selected users to dial numbers starting 91900. To do this, we must set up 2 short codes. The first one is a system short code that stops all general users from dialing numbers starting with 91900:

System short code: Short code | Right-click | New

• Short Code: 91900N

• Telephone: blank

• Feature: Busy

To allow a specific user to override the above system short code and dial 91900 numbers, we should add the following to their user short codes:

User specific short code: User | Double-click a specific user | ShortCodes tab | Right-click | Add

• Short Code: 91900N

• Telephone: 1900N

• Feature: Dial
