Abstract

A captioned telephone service (CTS) system for blocking spam calls includes a CTS server and a database. A CTS user's equipment is associated with a CTS number and an original phone number. The CTS server is configured to allow the user to elect to use an original number service and a call drop service. If the original number service is set, when the user places a phone call to a peer by using the CTS number, the original phone number, instead of the CTS number, is displayed as caller identification on a communications device of the peer. The CTS server assists the user to set up call forwarding and checks whether the call forwarding was successfully set. If the call drop service is set, the CTS server drops a call, directed to the CTS number. However, emergent calls or emergency related calls are excluded from the call drop service.
