SoliCall Work On removing Echo From Calls
by Alan Harten
September 30, 2008
Israel based SoliCall has been working on systems to reduce the amount of echo heard at both ends of a call, and have come up with two solutions to help curb this annoying reverb, Acoustic Echo Cancellation (AEC) and Call Monitoring.
AEC focuses on the actual voice at both ends of the line and makes adjustments to compensate for echo.
They monitor call quality using PBXMate, their VoIP/IP PBX quality control tracker.
PBXMate gathers detailed call statistics, looking for problems such as jitter, noise level and delay.
By analysing these error statistics they can improve call quality.
