Patent number: 6018574Abstract: A system and method for activation of an enhanced telecommunication service without a turn-on call by a subscriber. The present invention is described in the AIN environment, where an enhanced telecommunication service is set up for a directory number. The enhanced telecommunication service has an active state wherein the enhanced telecommunication service is applied to calls received for the directory number. The enhanced telecommunication service also has an inactive state wherein the enhanced telecommunication service is not applied to calls received for the directory number. The first call is directed to the directory number, where the enhanced telecommunication service is in the inactive state. A no answer condition from the directory number is detected with respect to the first call. In response to the detection of the no answer condition, the enhanced telecommunication service changes to the active state.Type: GrantFiled: October 27, 1997Date of Patent: January 25, 2000Assignee: BellSouth Intellectual Property CorporationInventor: Dale W. Malik

Patent number: 6011844Abstract: A point-of-presence (POP) call center system capable of answering, servicing, queuing and routing of calls at local points of presence to reduce communications costs and enhance operational efficiency for toll-free inbound call centers. The POP call center system includes a set of point-of-presence call center gateways distributed at points of presence close to the point of call origination that are connected by a virtual private network to premises call center gateways at business locations where the call centers reside.Type: GrantFiled: February 12, 1999Date of Patent: January 4, 2000Assignee: Callnet CommunicationsInventors: Prem Uppaluru, Mukesh Sundaram

Patent number: 6005933Abstract: Disclosed is a method for communication with no power feed in an exchange. (1) A calling subscriber unit transmits a special service code designating the disuse of a direct current loop together with the numeric information on the called subscriber unit to the exchange after formation of a direct current loop. (2) When the special service code is received, an on-hook transmission state in which the transmission and reception of an alternating current signal is possible between the subscriber line interface circuit and the calling subscriber unit even if no direct current loop is formed is established in the subscriber line interface circuit to which the calling subscriber unit which has transmitted the special service code is connected. (3) The calling subscriber unit disconnects the direct current loop, and the exchange maintains the speech path between the calling subscriber unit and the called subscriber unit even after the direct current loop is disconnected.Type: GrantFiled: December 23, 1997Date of Patent: December 21, 1999Assignee: Fujitsu LimitedInventor: Kenji Takato

Patent number: 5995607Abstract: An apparatus and a method for enhancing telephony trunk routing includes a call requirements assessor which identifies call requirements associated with a call request. In particular, the call requirements assessor recognizes call requests which are indicative of speaker-phone calls and conference calls. A comparison processor responds to call data received from the call requirements assessor bad comparing the call requirements of a particular call with the quality of service capabilities of an Internet telephony trunk and a non-Internet telephony trunk. A call request which includes a request for a speaker-phone call or a conference call triggers the comparison processor to instruct a call router to route a call via the non-Internet telephony trunk.Type: GrantFiled: October 14, 1998Date of Patent: November 30, 1999Assignee: Siemens Information and Communication Networks, Inc.Inventors: William Joseph Beyda, Shmuel Shaffer

Patent number: 5987112Abstract: A call-back service is disclosed having reduced post-dial delay. When a caller (12) initiates dialing of an international number of a called party (14), a dialer (28) monitors the dialed digits. Upon detecting a code corresponding to an international number, the dialer immediately launches a call to a node (16) in the caller's local exchange (18) while retaining the digits dialed by the calling party. The node then signals a call-back service platform (24) in a call back-country via a frame relay link (22) to launch a call through an ISDN network (26) back to the dialer. Thereafter, the dialer sends the digits to the call-back service platform which then launches a second call to the called party. The first and second calls are then bridged. By launching the call from the dialer upon detecting an international code in the number dialed by the calling party, the post dial delay is reduced.Type: GrantFiled: September 3, 1997Date of Patent: November 16, 1999Assignee: AT&T Corp.Inventors: Arvind S. Chakravarti, Edward D. Eng, Chi K. Lam, Yuk-Ming Lam, Henry H. Shen, Nancy Y. Tai
