pbxnsip - Using The Pre-Pay

Before a user can begin using the pre-pay calling card account, a dollar amount must be
specified in the user’s extension account:

1) Open the user’s extension.
2) Click the Registrations tab.
3) In the Credit for outbound calls setting, enter a dollar amount.

Important: If this field is left blank, the user will be allowed unlimited calling.

Note: Users can execute the Show Account Balance (*61) star code to determine
the number of minutes that are left on the pre-paid account.
