Abstract
A system, method and computer-readable medium for concurrent support of Voice Call Continuity (VCC) capabilities in both the enterprise space and the carrier space are provided. The enterprise VCC functionality is used when the user is located in the enterprise domain which does not impact the carrier's network while the carrier VCC capability is used when the user is located in the carrier domain to support seamless handover between the wireless networks that the carrier may offer. The carrier VCC anchoring point and the enterprise VCC anchoring point may communicate with each other to confirm and inform the other anchoring point that a call handover is occurring or will occur.
