An Internet telecommunication system in accord with the invention combines the capabilities of the Advanced Intelligent Network (AIN) with those of the internetwork commonly known as the Internet. Functions associated with the Internet Domain Name Server system are enhanced using AIN data and processing. Voice grade telephone calls from a fixed position Internet PC to a roaming wireless personal communication system are enabled. Home Location Register data from the control point of the AIN is forwarded into the Internet Domain Name Server for conditioning the IP lookup and addressing to determine the ultimate call routing. Internet calls may also be automatically completed by the system to addresses other than the ones entered by the caller.
