Control of calls over IP networks using an IP device connected to the network via a gateway

摘要

A system and method for call control wherein a call received at a communication device may be controlled through an IP device connected to an IP network over which at least a portion of the call was routed. The IP device is connected to the IP network via a control gateway. Using the SIP protocol, applications such as remote voice mail screening, call transfer to another phone prior to picking up the destination phone, midcall transfer to another phone, call logging, adding the call to an audio conference, putting the caller on hold, remote call hangup, ringing multiple phones on the incoming call, a screen popup on a PC that tells who is calling, providing information about the caller (address, phone number, picture, etc.), managing multiple devices and telephone numbers, controlling one button dialing from a nearby phone, voice dialing control, and midcall transfers can be controlled. <IMAGE>
