Abstract
A gateway interface device that can be provided with a buffer for temporarily storing a calling party's information which can be sent with the initial signaling message of a calling party on an IP network to establish a communication with a called party on a PSTN network. Subsequent to the receipt of the initial signaling message, and based on the calling party's stored information, the gateway interface can intercept a request for calling party information from the called party or a called party's end office. Once the request for calling party information is received by the gateway interface, the gateway interface can then generate a reply based on the calling party information stored in the buffer. Otherwise, the calling party information stored in the buffer can be removed from the buffer after a predetermined period of time.
