Abstract
Systems and methods for hosting communication sessions are described. A communication session between a first communication device and a second communication device is hosted in an Internet Protocol (IP) based packet data network in which a contact server functions as a bridge service between the first communication device and the second communication device. At least one of a communication link between the first communication device and the contact server and the second communication device and the contact server is initially a cellular communication link over a cellular network. The contact server analyzes at least two call quality characteristics of the cellular communication link and causes the communication device having the cellular communication link to handoff to an alternate communication link on an alternate network when at least one analyzed call quality characteristic of the cellular communication link crosses a threshold level.
