FXO Foreign Exchange Office. An FXO interface connects to the public switched telephone
network (PSTN) central office and is the interface offered on a standard telephone. An FXO
interface is used for trunks, tie lines, or connections to a PSTN CO or PBX that does not
support E&M signaling (when local telecommunications authority permits).
FXS Foreign Exchange Station. An FXS interface supplies ring, voltage and dial tone for
basic telephone equipment, keysets, and PBXs. The FXO interface is useful for off-premises
station applications.
Greeting The voice recording sent to the caller when a call is answered by voice mail or by
the auto-attendant; usually a single file, and not the concatenation of smaller phrases.

his or her voice mailbox, such as lighting the call-waiting lamp, paging the user, or dialing
