A system for call recovery, according to one embodiment of the present invention comprises a first device, a second device, a switch and a failover device. The first device, second device and failover device are communicatively coupled to the switch. The switch has a first communicative connection with a first device and a second communicative connection with a second device. The first and second communicative connections form a call between the first and second devices. The switch determines a recovery rule for the call and identifies the failover device based on the recover rule. The switch determines a call failure event during the call between the second device and the first device. The failover device builds a new communicative connection to the switch so that the failover device is communicatively coupled to the switch responsive to the call failure event, and connected on a call with the second device. |
