What method can be employed to reduce H.323 voice transmission delays?

Optimizing network speed is an effective method for reducing H.323 voice transmission delays because it directly addresses the fundamental components of data transmission. H.323 is a standard that governs audio, video, and data communications over IP networks. Delays often stem from insufficient bandwidth, high latency, or network congestion. By optimizing the network speed, ensuring that routers, switches, and the overall network infrastructure can handle voice traffic efficiently, you can minimize the time it takes for voice packets to travel from the sender to the receiver.

This includes measures such as increasing bandwidth, implementing Quality of Service (QoS) protocols to prioritize voice traffic, and reducing network congestion. All these factors contribute to a more responsive and real-time communication experience, ultimately leading to a reduction in transmission delays.

While other methods, such as adjusting frame size or reducing error correction, might seem to have some impact on delays, they could also compromise audio quality or lead to an increase in packet loss, further complicating the transmission process. Adding redundant paths can enhance reliability but does not directly address transmission speed or delay.
