Abstract:
Apparatus, methods, and computer-readable media for facilitating handling of voice over service fallback are disclosed herein.

The example method also includes initiating a timer when the TAU procedure fails, the timer associated with a first duration. The example method also includes re-initiating the TAU procedure based on an occurrence of a timer modification event, the re-initiating of the TAU procedure occurring before the first duration associated with the timer expires.
