An approach for enabling a customer to provision resources of a packetized voice service provider based on one or more customer conditions is described. A provision management platform receives a request for provisioning a domain name service as part of packetized voice service. In response to the request, the provision management platform prompts via a graphical user interface to obtain information for populating a service record of the domain name service. The provision management platform then generates the service record for storage corresponding to a customer account for the packetized voice service.
