✦ Synopsis

Soft-phone technology for Internet protocol (IP) voice is growing in importance. However, soft phones exhibit poorer quality than public switched telephone network (PSTN) phones. A goal is to improve that quality, perhaps even to the point that the communication experience is better than with PSTN phones. This letter presents an analysis of soft-phone performance and describes acoustic echo cancellation and other technologies that improve soft-phone performance.
