Poorly designed headphones or handsets can cause the signal to bounce which creates an echo. Tangled or broken wires, faulty headsets, poor design where microphone and earpiece sound can overlap are all examples of hardware issues. In this case, replacement of a faulty part or poor quality equipment will fix the echo.
If you are experiencing a ‘choppy’ sound israel telegram the problem could be that your router or overall network doesn’t have the bandwidth to handle your volume of packet transactions. One solution to this problem, outside of upgrading your hardware, is making sure that voice calls are properly prioritized on your network.
A choppy sound could also indicate that there is malware or spyware on one of the computers attached to the network. Be sure to run a test to detect if there are any malicious programs running in the background, as an infected computer in the network can negatively impact the sound quality of a VoIP connection.
Acoustic Echo Cancellation vs Echo Suppression
There are two acoustic systems within VoIP that handle echo. One is called Acoustic Echo Cancellation (AEC) and the other one is known as Acoustic Echo Suppression (AES).
AEC begins at the speaker, and looks for distortion, volume and the echo-path and subtracts the calculated echo from the microphone. AES on the other hand, checks the speaker, then the microphone and mutes the microphone when echo is detected. Both systems can be used simultaneously, but for stable systems, AEC is often the better solution. Low resource systems typically rely on AES.
While echo is a common problem – the underlying cause can often be readily diagnosed by looking for hardware issues or electrical imbalances. Persistent echo can also be managed by implementing one or both of these acoustic solutions, or by working with your service provider to resolve any issues on their end.
