Barring a User From Making Any External Calls

For each user, User > Telephony > Supervisor Settings > Outgoing Call Bar can be selected to stop that user from making any external calls.

Barring Particular Numbers/Number Types

The system allows short codes to be set at user, user rights, system and least cost route.  These have a hierarchy of operation which can be used to achieve various results. For example a system short code for a particular number can be set to busy to bar dialing of that number. For a specific user, a user short code match to the same number but set to Dial will allow that user to override the system short code barring.

System short codes are used to match user dialing and then perform a specified action. Typically the action would be to dial the number to an external line. However, short codes that match the dialing of particular numbers or types of numbers can be added and set to another function such as Busy. Those short codes can be added to a particular user, to a User Rights associated with several users or to the system short codes used by all users.

Using Account Codes

The system configuration can include a list of account codes. These can be used to restrict external dialing only to users who have entered a valid account code.

• Forcing Account Code Entry for a User - A user can be required to enter an account code before the system will return dialing tone. The account code that they enter must match a valid account code stored in the system configuration. The setting for this is User > Telephony > Supervisor Settings > Forced Account Code.

• Forcing Account Code Entry for Particular Numbers - Each system short code has a Force Account Code option. Again the account code entered must match a valid account code stored in the system configuration. for the call to continue.

Barring External Transfers and Forwards

A user cannot forward or transfer calls to a number which they cannot normally dial. In addition there are controls which restrict the forwarding or transferring of external calls back off-switch. See Off-Switch Transfer Restrictions.
