METHOD AND APPARATUS FOR ECHO SUPPRESSION

摘要

The present invention relates to a cost-effective way of minimizing an echo arising in the PSTN network in a connection at least partially connected through a digital network, with minimum processor capacity required but still maintaining a high quality. The object of the present invention is to minimize, in a cost effective way, the echo while minimizing the processing requirements. The above problem of minimizing an echo arising in an analogue part of a connection is solved by switching to prevent the sound from passing from the analogue to the digital side.
