Abstract
Methods, systems, and computer program products for providing caller ID and call waiting and for switching or toggling between active and waiting calls using SIP are disclosed. According to one method, a first call is established between a first phone and a SIP termination. The first call is established using the first media connection between the SIP termination and a media gateway and a second media connection between the media gateway and the first phone. During the first call, signaling for establishing a second call to SIP termination is received. In response to the signaling, caller ID information for the second call is communicated to the SIP termination. A hook flash is received from the SIP termination. In response to the hook flash, the SIP termination is connected to the second phone using the first media connection and a third media connection between the media gateway and the second phone.
