Converged voice services

摘要

Novel tools and techniques for providing a subscriber with converged voice services, in which calls to one of the subscriber's telephone numbers is routed to some or all of the subscriber's telephone numbers (e.g., sequentially or simultaneously, depending on system configuration and/or subscriber preference). Some implementations employ a VoIP switch to handle call distribution among the subscriber's various phone lines, even if some (or all) of the subscribers telephone lines are not VoIP lines. In such implementations, upon receiving an incoming call directed to one of the subscriber's lines, a service switching point will route the call to a VoIP switch. Instructed by an application server, the VoIP switch will set up call legs (e.g., via the PSTN) to one or more of the subscribers' telephone numbers. Optionally, when one of the call legs is answered, the application server will instruct the VoIP switch to disconnect the other call legs.

主权项

1. A system for providing converged voice services, the system comprising:
a service switching point (SSP) configured to:
receive, via a public switched telephone network (PSTN), a call from a calling party to a first telephone number of a plurality of telephone numbers associated with a converged voice services subscriber, the plurality of telephone numbers further comprising a second telephone number;fire a termination attempt trigger (TAT) in response to receiving the call; an application server configured to:
detect the TAT; anddetermine, in response to the TAT, that the subscriber has configured simultaneous ring services;send a message to the SSP instructing the SSP to forward the call to a voice over Internet Protocol (VoIP) switch; the VoIP switch configured to:
receive the forwarded call from the SSP;send a first SIP INVITE, in response to receiving the forwarded call; wherein:
the application server is further configured to:
receive the first SIP INVITE; andsend, in response to receiving the first SIP INVITE, a plurality of additional SIP INVITEs, the plurality of additional SIP INVITEs comprising an additional SIP INVITE corresponding to each of the plurality of telephone numbers and including a first additional SIP INVITE corresponding to the first telephone number and a second additional SIP INVITE corresponding to the second telephone number; and the VOIP switch is further configured to:
receive each of the plurality of additional SIP INVITEs;create a plurality of call legs via the PSTN, the plurality of call legs comprising a call leg corresponding to each of the additional SIP INVITEs and including a first call leg to the first telephone number and a second call leg to the second telephone number; andconnect the forwarded call with at least one of the call legs.
