Abstract
A method to translate between Public Switched Telephone Network (PSTN) numbers and Voice over Internet Protocol (VoIP) addresses without performing an address translation database lookup. A network gateway receives and translates a first endpoint identifier associated with a destination client device to a second endpoint identifier associated with the destination client device. The first endpoint identifier is either a PSTN number or a VoIP address comprising at least the PSTN number and a predefined suffix and the second endpoint identifier is the other of the PSTN number and the VoIP address. The network gateway translates the first endpoint identifier to the second endpoint identifier without performing an address translation database lookup, by either adding the predefined suffix to or removing the predefined suffix from the first endpoint identifier. The network gateway generates and transmits a second session initiation message containing the second endpoint identifier to facilitate establishment of the session.
