Termination Events
• CCEV_SETBILLING - indicates that the billing information for the call has
been acknowledged by the network. This event is returned only when the
AT&T Vari-A-Bill feature is used.
• CCEV_TASKFAIL - indicates that a request/message was rejected by the
firmware. Typically, this event is triggered by an incorrect function call
during the call.

Cautions
• This function is available only on the AT&T network and only for the PRI
4ESS protocol.
• cc_SetBilling( ) may not function in all service-provider environments.
Check whether retrieving billing information is an option with the service
provider.
