  • Adjunct call handling for accessing adjunct-based capabilities platform
    Patent number: 5550911
    Abstract: A method to allow certain types of adjunct applications for telecommunications networks that require caller interaction during call setup to temporarily access the adjunct and then be released back to the network for routing to the final destination. Specifically, when the call enters the network, the network originating switch redirects certain calls to the adjunct. The adjunct may be locally homed directly off the originating switch or may be homed remotely off a centrally located switch. Once the call has been routed to the adjunct and caller interaction has been completed, the adjunct releases the voice connection back to the switch which then routes the call to its final destination.
