During a technical problem on a VOIP call, the problems that can occur are the following:
- choppy or jerky voice (you don't hear all the words of your interlocutor),
- blank or larger break in the conversation,
- discrepancy between your questions and the answer of your interlocutor or you speak at the same time after a sentence (also called satellite effect).
These 3 problems usually come from a network problem between you and your interlocutor.
Since a call is a continuous stream of data (sound), the slightest disturbance in this stream will generate a sound distortion that you can sometimes perceive.
Several techniques or computer systems make it possible to avoid or limit most of these problems to maintain optimal sound quality, however, depending on the calls or if your correspondent is on a mobile, the problem can occur and come from any chain element.
