Systems and method for providing application layer fault tolerance in a VoIP architecture is shown and described. The method includes associating a virtual network address with one of a first communication device and second communication device, receiving a message from a network element, detecting a fault on an active one of the communication devices, and associating the virtual address with the other of the communication devices. Each of the first and second communication devices is coupled to a VoIP network. The virtual network address is associated with the active one of the communication devices. The detection of the fault occurs when the active communication device is at a first execution point of an application executing on the active communication device. When the virtual address is associated with the other communication device, the other of communication devices continues to provide the service from the first execution point.
