In a computer, a test script is received that includes a first set of commands to be provided to an Internet protocol (IP) telephone. The test script is parsed to obtain the first set of commands. Parameters that identify the telephone are obtained. The parameters and at least one of the first set of commands are used to obtain at least one corresponding second command from a conversion table. A command script is generated to be executed by the telephone, the command script including the at least one corresponding second command.
