Introduction

VoIP (Voice Over Internet Protocol) technology has revolutionized the way we communicate, enabling voice communication through IP-based networks, both internet and intranet. This technology functions by converting sound into digital data that can be sent through a package network. One of the main indicators in assessing sound quality in the VoIP system is the delay time, which is a pause between shipping and receiving votes. This delay time can vary depending on the type of codec used. Different codec has a variety of speeds and processing, thus affecting one-way delay in VoIP communication.

Understanding One-way Postponement Time

In this analysis, we will discuss the one-way postponement time in the VoIP call between the UMTS (Universal Mobile Telecommunications System) and PSTN (Public Switched Telephone Network) network using several types of CODEC. It is essential to understand that each codec has unique characteristics and affects not only delay, but also the sound quality produced. By choosing the right codec, we can minimize postponement time and improve the quality of voice communication.

The Importance of Codec Selection

The results of the analysis show that along with the increase in codec sampling speed, the one-way delay produced is getting smaller. This means codec with a higher sampling speed can process and transmit sound more efficiently. In addition, better codec also produces clearer and cleaner sound quality, improving overall user experience.

Codec Selection in UMTS and PSTN Networks

This analysis also highlighted the importance of selecting the right codec in the implementation of VoIP, especially in the context of UMTS and PSTN networks. The UMTS network, which often has larger bandwidth and lower latency, may be better in supporting codec with high sampling speeds. On the other hand, PSTN, which is a traditional telecommunications network, may have a limit in terms of bandwidth, so the selection of codec must be more careful in order to maintain the quality of communication.

Conclusion

Overall, understanding of the one-way postponement in VoIP calls is very important to improve the quality of voice communication. By conducting a careful analysis of the use of various types of codecs, we can achieve significant delay reduction and, at the same time, increase user satisfaction in communicating. To optimize voice communication in modern networks, the appropriate codec selection is a key factor that cannot be ignored.
