Abstract:

A method and system for customizing caller ID information can be used in a call center or other telephony system to present customized caller ID information to a called party independent of the telephone line from which the call is made in the call center. The system retrieves at least one call record including a telephone number to be called and a customized caller ID telephone number associated with the call record. The number to be called and customized caller ID number are placed in a setup message formatted using an Integrated Services Digital Network (ISDN) protocol. The setup message is sent to the Public Switched Telephone Network (PSTN) to establish a telephonic connection with the called party. If the called party subscribes to the caller ID service, the customized caller ID telephone number and any associated information will be presented to the called party.

Abstract:

Described are computer-based methods and apparatuses, including computer program products, for packet signaling content control on a network. The content control includes two sets of filters—an ingress filter set and an egress filter set. For packets coming into an internal network, the packets (e.g., SIP packets) are filtered by an ingress filter associated with the external network and which determines whether to discard sets of information from the packet description information (e.g., a header, an optional header). The packet is also filtered by an egress filter associated with the internal network and which determines whether to discard sets of information from the packet description information. The packet is transmitted to the internal network. For packets leaving the internal network, the filtering occurs in the opposite direction (e.g., egress filter associated with the internal network and then ingress filter associated with the external network).
