  • Method and apparatus for performing internet protocol address resolutions in a telecommunications network
    Patent number: 6801523
    Abstract: A method and apparatus for performing directory number/Internet Protocol (IP) address resolutions to facilitate voice over IP communications. A message requesting the IP address of an IP gateway is built at an originating Time-Division Multiplex (TDM) switch (that forms part of either a private or public network). The message is forwarded over a TDM telecommunications network to a terminating TDM switch, where the requested IP address information is retrieved. The IP address is forwarded across the TDM telecommunications network to the originating TDM switch. The IP address is then used to establish a call across an IP network. By using existing TDM protocols and infrastructure to request and retrieve IP gateway information, the present invention does not suffer from the scalability problems inherent in other DN/IP address resolution solutions.
