A system, method, and apparatus for transmitting a packet from a server to a wireless client, using direct digital calls, wherein the server initiates the call are presented. The server transmits a packet to addressed to an Internet Protocol (IP) address associated with the wireless client. The packet is received by a wireless application gateway which maintains a table correlating IP addresses with mobile services integrated services digital network (MSISDN) numbers or mobile identification numbers (MIN). The MSISDN/MIN number is then used to request routing information. In response to the request, a dynamic IP address and a traffic channel are allocated to the wireless client. The dynamic IP address is transmitted to the wireless application protocol gateway. Upon receiving the IP address, the wireless application protocol gateway transmits the digital data communication towards the IP address. The digital data communication is received by a serving mobile switching center which causes the digital data communication to be transmitted to the wireless client using the allocated traffic channel.
