A method, an apparatus, and a computer program product for wireless communication are provided in connection with establishment of packet based communications through use of circuit switched signaling messages. In one example, a communications device is equipped to receive, by a circuit switched (CS) interface associated with a target device, a first CS signaling message from an originator device, determine whether to initiate the packet data session in response to receipt of the first CS signaling message, and establishing, using a packet switched (PS) interface associated with the target device, an internet protocol (IP) communication session in response to communication of an IP connection request between the originator device and the target device upon a determination to initiate the packet data session. In an aspect, the first CS signaling message may include an indication prompting the target device to initiate a packet data session.
