Abstract
A method and system for directed call establishment to anchor selected cellular calls in a Voice over Internet Protocol (VoIP) or an IP Multi-Media Subsystem (IMS) network employs a mobile handset application client to interrupt selected cellular call initiations and request a directed call establishment number from a converged services node. A call placed to the directed call establishment number creates a call signaling path through the converged services node in the VoIP or IMS network, which can then exercise control over the call to provide enhanced call services. The converged services node completes a call connection to the original called number in a manner transparent to the user of the mobile handset.
