METHODS AND SYSTEMS FOR LOCATING REDUNDANT TELEPHONY CALL PROCESSING HOSTS IN GEOGRAPHICALLY SEPARATE LOCATIONS

摘要

Methods and systems for providing redundant telephony call processing in geographically separate locations are disclosed. First and second telephony call processing hosts (100,104) are provided in first and second geographic locations (102,106) separated from each other. The telephony call processing hosts are located on the same LAN, which is also divided among the geographically separated locations. The geographically separate LAN or LANs are bridged using either a customer's IP network (122) or isolation routers associated with the redundant telephony call processing hosts.
