A one-to-many wireless telephone communication system includes a transmitting telephone that transmits voice packets in, e.g., CDMA to a base station in an IP-based infrastructure. The base station converts the CDMA packets to IP and sends them through the infrastructure to a communication manager, which copies the packets as many times as necessary for the recipient telephones in the group and sends the IP packets back through the infrastructure using the IP addresses of the recipients. The base stations receiving the IP packets transform them to voice packets and transmit the voice packets to the recipient telephones, thereby relieving the telephones from having to support IP.
