ENHANCED IP PHONE OPERATION

摘要

An enhanced IP telephone taking advantage of the many call-related functions provided by existing PBX systems. The enhanced IP telephone includes a thin computer telephony integration (CTI) client (34) transmitting to a CTI server (38) a command associated with a particular call-related function provided by a PBX unit (36). The CTI server (38) translates the command to a PBX command, and transmits the PBX command to the PBX unit (36) for providing the particular call-related function to the enhanced IP telephone. Instead of the thin CTI client (34), the enhanced IP telephone may include an enhanced IP signaling protocol stack (64) for accessing the PBX functionality using its signaling protocol. A CTI translator (62) translates the enhanced signaling command to a CTI command for transmitting to the CTI server (58).
