Methods, systems, and storage mediums for implementing self-provisioning telephony services are provided. A method includes storing an access number at a service control server that services a local exchange carrier switch. The method also includes assigning a toll-free number to a customer account and distributing the toll-free number and access number to the corresponding customer. The method further includes receiving, at the local exchange carrier switch, a call from a customer, the call identified as the access number. The method also includes routing the call to a server and, absent human intervention, the server accessing the toll-free 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 number. The method also includes transmitting the provisioning order to the service control server, the service control server activating the toll-free number for the customer account.
