A method to be executed in a session initiation protocol (SIP) environment is provided that includes initiating a conversion process that involves a change from a first communications platform to a second communications platform. One or more routing tables associated with the first communications platform are then dumped. A conversion script is executed such that one or more patterns associated with a dial plan corresponding to the second communications platform are provided in a dial plan format. One or more files associated with the dial plan are loaded into one or more endpoints that are designated to change to the second communications platform.
