Abstract
An approach for call failover to a packetized voice session is described. Impending signal failure is detected on a cellular link supporting a cellular call with a user device. A failover procedure is initiated in response to the detection, wherein the failover procedure includes detecting presence of a wireless data connection, and terminating the cellular call and concurrently activating a voice call application to establish a packetized voice session over the wireless data connection with the user device.
