Publication number: 20130223291Abstract: A method and apparatus for enabling providers of PSTN toll free services to stagger simultaneous transmission of call setup signaling messages into an IP based teleconference bridge, supported by a VoIP network, by suspending a subset of calls and placing them on hold while placing other calls to be connected to the conference bridge are disclosed. The PSTN network can stagger calls by limiting the number of call setup signaling messages to be sent to the VoIP network within a predefined period of time interval and spread all the calls over multiple of such predefined periods. Prerecorded announcements or music can be played while the calls that have been placed on hold are in queue.Type: ApplicationFiled: April 1, 2013Publication date: August 29, 2013Applicant: AT&T Corp.Inventor: AT&T Corp.

Publication number: 20130208614Abstract: The present invention is a technique for provisioning and assessment of voice quality in Internet Protocol (IP) voice applications. A predetermined quality of service (QoS) is received from a user in the form of an acceptable packet loss. The technique measures current packet loss and delay in the network and in the terminal, and determines and optimum play-out delay for the use by a play-out adaptation routine. An actual QoS is reported back to the user. To enhance packet delay and loss measurement, a QoS engine component is placed on the terminal side of the packetizer, therefore including packetizer losses in any measurement of the network.Type: ApplicationFiled: March 18, 2013Publication date: August 15, 2013Applicant: AT&T Corp.Inventor: AT&T Corp.

Publication number: 20130155910Abstract: The present invention enables users of packet-switched network services, e.g., VoIP network services, to hear a very gentle whispering tone that quietly conveys the identity of the calling party when they are engaged in conversation and to receive a call-waiting signal. The tone is audible only to the called party but does not mute the ongoing conversation path. This enables subscribed users to hear their ongoing conversation while receiving the whispering tone.Type: ApplicationFiled: February 18, 2013Publication date: June 20, 2013Applicant: AT&T Corp.Inventor: AT&T Corp.

Publication number: 20130128745Abstract: The present invention is a system and method for failing over from a current network access medium to an alternative network access medium. A customer premises equipment (CPE) box has ports for connections to a network through several network access media, such as high speed cable connections, DSL connections and dial-up connections. QoS parameters for each of the connections are monitored from a bandwidth manager remote from the CPE box. When it is determined that a fail-over would be beneficial, a message is sent from the bandwidth manager to the CPE box containing a command to fail-over and an identity of the alternate network access media.Type: ApplicationFiled: January 21, 2013Publication date: May 23, 2013Applicant: AT&T Intellectual Property II, L.P., vis transfer from AT&T Corp.Inventor: AT&T Intellectual Property II, L.P., via transfer from AT&T Corp.

Publication number: 20130125207Abstract: The invention describes a method for hardening a security mechanism against physical intrusion and substitution attacks. A user establishes a connection between a network peripheral device and a network via a security mechanism. The security mechanism includes read only memory (ROM) that contains code that initiates operation of the mechanism and performs authentication functions. A persistent memory contains configuration information. A volatile memory stores user and device identification information that remains valid only for a given session and is erased thereafter to prevent a future security breach. A tamper-evident enclosure surrounds the memory elements, which if breached, becomes readily apparent to the user.Type: ApplicationFiled: December 11, 2012Publication date: May 16, 2013Applicant: AT&T Corp.Inventor: AT&T Corp.
