Abstract
A method, system and apparatus for managing call handoff are provided. A mobile device engaged in a first media session over a first transport determines a second transport is available. A reflected media session is established via an echo server over the second transport. Quality of the reflected media session is evaluated by determining a call metric based on call transport data received at the mobile device from the mobile device (itself) in the reflected media session. Call handover is requested from the first media session to a second media session over the second transport when the call metric indicates that the quality of the reflected media session meets a threshold.
