Abstract
Messages sent from an initiating device to a called device to establish a telephonic communication session between the initiating device and the called device are received at a network device. One of a first network or a second network is selected to establish a first communication path of the telephonic communication session. The first network comprises an Internet Protocol network to which the initiating device and the called device are connected, and the second network comprises a public switched telephone network. Messages are sent to the called device via the one of the first network or the second network to establish the first communication path. A second communication path is established between the initiating device and the called device through another of the first network or the second network. At least a subset of data also being sent over the first communication path is sent via the second communication path.
