Abstract
Systems and methods are provided herein for transferring an active voice call to a packet communication network. In a particular embodiment, a method provides establishing a voice call having an initial signaling channel and an initial voice channel between a first wireless device and a second wireless device over a first and second wireless access system. The method further includes establishing a new signaling channel for the voice call between the first wireless device and a separate packet network. Also, the method provides extending the new signaling channel for the voice call from the separate packet network to the second wireless access system over the first wireless access system. Furthermore, the method includes using the new signaling channel to establish a new voice channel for the voice call over the separate packet network, wherein the first wireless access system remains in the new signaling channel.
