A self-provisioning telephony service includes assigning a toll-free telephone number to a customer account for a customer of a telecommunications provider, distributing the toll-free telephone number and an access number to the customer along with an invitation to provision a toll-free telephone number service, and receiving, at a local exchange carrier switch, a call from the customer. The access number is identified by the local exchange carrier switch for the call in response to performing a call number translation. The telephony service also includes accessing, by a server, the toll-free telephone number identified for the customer account and generating a provisioning order that includes a customer telephone number from the customer account and the toll-free telephone number. The telephony service further includes transmitting the provisioning order to a service control server, the service control server activating the toll-free telephone number for the customer account. |
