Inter-network line level adjustment method and system |
摘要 |
An inter-network line level adjustment system includes a switch (SW1) and a processing unit (24) for identifying calls between a remote telephone network and a local telephone network. Echo cancellers (20) and/or speech coders (22) collect line level data associated with the identified calls. The processing unit (24) determines statistical properties of the collected line level data. Finally, the processing unit (24) instructs the echo cancellers (20) and/or speech coders (22) to adjust, based on the determined statistical properties, line levels of future calls between the remote telephone network and the local telephone network to a desired line level.
