Abstract
The paper discusses voice transmission quality issues relating to interworking between VoIP and PSTN "legacy" networks. The evolution of voice quality with technological progress in the PSTN from its inception to the present day VoIP systems is described and this sets the scene for discussion of echo control and silence removal in case study examples.
