Abstract
An induced loss value is retrieved from a configuration file of an MTA device. The loss value is provided to a signal generator that generates call progress/alerting signals and FSK signals in the MTA telephony device. To mitigate the imbalance between incoming voice signal levels and call progress/alerting signals that may occur because the call progress/alerting signals are not generated at a level equal to that of the incoming voice signals, the loss/attenuation amount from the configuration file is used to adjust the levels of the generated call progress/alerting and FSK signals by a corresponding amount before they are attenuated along with the incoming voice signals.
