Toshiba is using Broadcom's IP phone chip in its enterprise IP telephones. Broadcom's BCM1113 IP phone chip features an integrated Ethernet switch (two port) capability that enables manufacturers to develop IP phones that use the Ethernet switch connections of the IP Phone to support both voice calls through the phone and data traffic to the PC. This capability eliminates the need to have two Ethernet connections in an office or to add switch ports in the wiring closet to support VoIP. http://www.broadcom.com
