Path of TeleBlock® Call –
1. A proprietary web-based user interface is created for each TeleBlock® subscriber for database administration purposes.
2. All available federal, state and wireless DNC lists are secured and automatically updated according to mandated update intervals.
3. Information such as allow list data, in-house DNC list data, the individual state and wireless DNC lists to screen against, the federal DNC registry NPAs to screen against, etc. is sent to the TeleBlock® application by the subscriber via their web-based user interface.
4. All DNC data is compiled via the web-based user interface and sent as incremental data files to the TeleBlock® database.
5. The TeleBlock® database resides on VeriSign®'s redundantly located Advanced Transaction Look-Up And Signaling (ATLAST) system, "Do-Not-Call Platform", which is accessible via both SS7 and IP technologies. Citadel Telephone Company queries TeleBlock® via IP technology.
6. Calls originate from the end-user telemarketer's calling equipment and ride available Citadel provided telephone line and trunk group facilities to a Citadel softswitch switch.
7. The physical calls are held at the Citadel softswitch while an IP call information packet containing an originating number and terminating (dialed) number pair goes off to the TeleBlock® platforms for a database look-up. Based upon the ANI (telephone number) or AUTH Code (trunk group) calls originate from, the corresponding client specific database is queried. The terminating number is screened against the corresponding DNC database based upon the campaign applied to the originating telephone line or trunk group at that point in time.
8. If the terminating number does not appear in the applied DNC database campaign, then a TeleBlock® look-up response is routed back to the Citadel softswitch, where a call is physically held, with a 'Continue' message. A 'Continue' message triggers a call to go off to its final destination, or called party.
9. If the dialed number appears in the applied DNC database campaign, then a TeleBlock® look-up response is routed back to the C.O., where a call is physically held, instructing call to route to a pre-determined switch based announcement. The caller or calling equipment will hear a 'restricted number' message based upon messaging option selected, and dispose of the call accordingly.
