  • Patent number: 10939290
    Abstract: This invention shows a method for operating a voice communications network that comprises dynamically associating a private number with at least one public number of a circuit-switched voice communication network, authenticating a user of a private number without reliance on a static reproducible data code, receiving an incoming call to the public number and routing the incoming call from a caller to the private number. The method also shows the generation of an outgoing call from the private number and passing the outgoing call through the public number while generating calling party information to a target which preserves the privacy of the caller, and altering an associating of the private number and at least one public number. The system therefore acts as a proxy with authentication by means of dynamic code security. The caller and the user of the private number share seamless round-trip telephone communications while preserving the anonymity of the user of the private number.

  • Patent number: 8767934
    Abstract: A topic is associated with a temporary communications address such as a temporary telephone number. This assignment may be effected by the user when the temporary address is obtained by the user. Illustratively, a user who simultaneously uses a plurality of temporary addresses associates a different topic with each of those addresses. When a caller calls the temporary address, the call is redirected to the user's real address and the user receives the topic that is associated with that temporary address, and preferably also the called temporary address itself, along with the redirected call, and this information is either displayed or announced to the user. The information provides context for the call to the user, and may optionally be captured in call logs. Illustratively, when the user initiates a call via the temporary address or the topic, the temporary address or the topic is provided to the called party as the caller ID information. The user's identity is thus kept secret.

  • Patent number: 8300782
    Abstract: A security plan for telephone clients allows the client to authenticate itself by sending a coded sequence of DTMF digits to a PBX at the beginning of each call. When the idle client telephone receives a call, it sends a coded DTMF sequence to the PBX. If the client makes a feature invoking call to the PBX while active on the first call, the client will be prompted for the security sequence. The client must send the same sequence of DTMF digits as for the first call. The first call is authenticated by virtue of being a call from the PBX to the telephone. The second call is authenticated by sending a DTMF sequence that matches the one sent with the first call. A call that fails authentication is dropped. The security plan for clients constrains the client to using a callback to originate a call from an idle telephone.

  • Patent number: 7831038
    Abstract: The present invention overcomes interface problems between proprietary handset ports on telephone base units and voice/data accessory products by allowing a user to automatically calibrate the telephone accessory product for an optimal interface match with the intended telephone base unit. This is accomplished through the use of a “Smart Interface Technology” (SIT) integrated chip set consisting of a full custom analog and semi-custom digital integrated circuit. The SIT incorporates three different methods for “learning” the characteristics of 4-wire port modular interfaces found in all telephone station sets. Basically, these methods determine the appropriate 4-wire terminal configurations, the transmit and receive channels of the intended telephone base unit, and adjust the channel sensitivities until an optimal and clear signal is provided for the user.

The security plan for clients constrains the client to using a callback to originate a call from an idle telephone.

  • Patent number: 7688959
    Abstract: A system and method for allowing remote callers to access a secure telephone network maintains a registry (i.e. a database) of all remote callers that have access to the network. The registry contains an electronic serial number (ESN) and a personal identification number (PIN) for each remote caller. The ESN is typically the serial number of the callers cellular telephone. Alternatively, the ESN is a phone number of the remote caller's telephone. To establish a connection, the remote caller calls a private branch exchange (PBX) of the secure network. Upon receiving the call, the PBX compares the ESN and PIN of the remote caller with the ESN and PIN stored in the registry. If a match is found, the PBX authenticates the remote caller and allows the connection. The remote caller may have full access or access limited by a connection policy.

  • Patent number: 7627105
    Abstract: A first list and a second list of identifications are established, with which a telemarketing advertisement or no undesirable telemarketing advertisement is expected. The identification of the caller an incoming call is compared to the identifications in the list. If the identification of the call is not found in the lists, the call is routed to a call processing which enables the reception of a telemarketing advertisement to ascertained and, based on the result of that determination, the lists are correspondingly updated. The calls for which the identification of the caller is recorded in the second list are routed to the called party and the calls for which the identification of the caller is recorded in the first list are rejected. Such protection against telemarketing is particularly efficient in the context of an industrial operation with numerous human resources and for lines on which several calls can be simultaneously carried.
