Abstract
A method for setting up a voice call over an IP network is described. The method first initiates an IP voice call to a called device connected to a telephone line. The method then determines whether the called device is already connected to the IP network. If the called device is not already connected to the IP network based on the determining step, the method will initiate a telephone call with an associated telephone signal through the telephone line to the called device, to alert the called device that an IP voice call is pending.
