Abstract
A telephone system may include a telephone receiver and a base unit. The telephone receiver may include a first electrical contact and a second electrical contact configured to be electrically grounded. The first electrical contact may be either coupled to the second electrical contact or electrically floating. The base unit may be configured to be coupled to the telephone receiver over a wired connection. The base unit may be configured to electrically ground the second electrical contact by way of the wired connection. The base unit may also be configured to determine an identification of the telephone receiver based on whether the first electrical contact is electrically grounded or electrically floating.
