Abstract
Receipt of a failure response message in response to a domain transfer attempt is cached at a mobile device. The mobile device retains information related to the domain to indicate that the domain does not support anchoring and, thus, does not support voice call continuity. The mobile device might not attempt domain transfer for subsequent calls in the same area. In an aspect, after expiration of a configurable interval, the mobile device can re-attempt domain transfer to determine if anchoring is now supported by the domain. If the domain now supports anchoring, the identification of the domain can be removed from the domain listing.
