A system and method for providing secure configuration file exchange is disclosed. The system may include a Voice over Internet Protocol (VoIP) device having a receiver and a processor, and the VoIP device may be configured to: receive, at the receiver, an encrypted first configuration file from a server using a default Uniform Resource Locator (URL) stored in the VoIP device; decrypt, at the processor, the first configuration file using a default key stored in the VoIP device; apply, at the processor, a first set of profile parameters stored in the first configuration file, and the step of applying may include updating the default URL and the default key in the VoIP device with a new URL and a new key stored in the first configuration file; receive, at the receiver, an encrypted second configuration file from the server using the new URL; decrypt, at the processor, the second configuration file using the new key; and apply, at the processor, a second set of profile parameters stored in the second configuration file in order to provide network service from the server to a customer premise equipment (CPE) communicatively coupled to the VoIP device.
