Abstract
A system for verifying the identification of a device. A codec is configured to measure at least one electrical characteristic of a device connected to a jack and to identify the device based on the measured electrical characteristic. An updateable database is populated with the electrical characteristic of at least one device whose electrical characteristic was measured by the codec but not correctly identified by the codec and a software routine is responsive to the measured electrical characteristic and configured to adjust the codec's identification of the device based on the electrical characteristic stored in the database to correctly identify the device.
