A method and apparatus, e.g., a headset, for notifying a user of a muted state of a primary microphone during a call when the user speaks with the primary microphone muted. The method includes performing a noise cancellation algorithm (ENC) on an output signal from the primary microphone and an output signal from an additional microphone capturing sounds around the user to suppress ambient noise at the user's location. Further, the output signal from the primary microphone with the primary microphone muted is processed based on a voice activity detection (VAD) algorithm with a processor system. The VAD algorithm is used to determine whether speech is present, and then it is determined whether additional conditions are met. Finally, a mute state notification is provided to the user only if speech is present and the additional conditions are determined to be met. The method is well suited for headsets, for example, where various noises at the mouth microphone may otherwise cause unintended and disturbing mute state notifications. Using the VAD algorithm, it is possible to ensure that notifications are triggered only by speech, and additional conditions can be used to eliminate or at least reduce intrusive notifications in a way that intelligently provides mute status notifications, for example based on speech activity of other participants on the call or based on speech around the user.

A method of determining the location of a disconnection on a digital subscriber line, in particular a VDSL line, where the line has a number of nodes or connection points along it. A statistical model is generated from a population of lines that maps the loop (line) lengths of each of those lines obtained by line test measurements (such as single ended line test traces - SELT traces) against the corresponding loop lengths obtained from inventory data. The model is then used to determine a predicted loop length by mapping a measured loop length (taken from line test measurements) onto an inventory loop length using the model. Knowledge of the node positions on the line is then used to give a probability a line disconnect occurring at a given node by mapping the predicted loop length onto the node positions.

A session border controller (SBC) that is separate from a telephony server associated with a destination telephony address receives an initiation request for a telephone call from an originating telephony device to the destination telephony address. The SBC attempts to connect the originating telephony device to the telephony server. Upon failing to connect the originating telephony device to the telephony server, the SBC connects the originating telephony device to a backup address associated with a distribution group. The SBC causes connection of the telephony device to a device of the distribution group via the backup address.

Detecting a short disconnection in a digital subscriber line, for example where the disconnection is near the DSLAM. A SELT UER trace is obtained from the digital subscriber line. The trace is analysed to determine its smoothness, as relatively smooth traces result from shorter lines. The smoothness measure can be calculated by applying some function to the differences of the amplitude between successive frequency tones. Two examples of functions that have been found to work well are a sum and a standard deviation. The result of the function can be compared to a threshold to determine if a short disconnection has occurred. Such a situation can occur when a cable has been disconnected from a patch panel for example.
