A company's employees are experiencing poor audio quality during VoIP calls, with voices breaking up irregularly. The network technician finds no significant packet loss and adequate bandwidth. What is the MOST likely cause of the voice quality issues?
The firmware on the router is outdated.
The network interface cards (NICs) are faulty
The network is experiencing jitter.
The signal strength for the wireless phones is low.
Jitter is the variation in time between data packets arriving, caused by network congestion, timing drift, or route changes. Jitter can lead to packets arriving out of order, causing choppy audio in VoIP calls. In contrast, a faulty NIC usually affects the entire computer's network connection, not just voice call quality. Signal strength primarily impacts wireless connections, and while poor signal strength can cause various issues, it does not explain the irregular voice break up if the signal is consistently strong. Additionally, outdated firmware could cause problems, but it is less likely to affect packet timing and result in jitter.
