Abstract
5G technology is spreading extremely quickly. Many services, including Voice Over Internet Protocol (VoIP), have utilized the features of 5G technology to improve their performance. VoIP service is gradually ruling the telecommunication sector due to its various advantages (e.g., free calls). However, VoIP service wastes a substantial share of the VoIP 5G network’s bandwidth due to its lengthy packet header. For instance, the share of the packet header from bandwidth and channel time reaches 85.7% of VoIP 5G networks when using the IPv6 protocol. VoIP designers are exerting considerable efforts to solve this issue. This paper contributes to these efforts by designing a new technique named Zeroize (zero sizes). The core of the Zeroize technique is based on utilizing the unnecessary fields of the IPv6 protocol header to keep the packet payload (voice data), thereby reducing or “zeroizing” the payload of the VoIP packet. The Zeroize technique substantially reduces the expanded bandwidth of VoIP 5G networks, which is reflected in the wasted channel time. The results show that the Zeroize technique reduces the wasted bandwidth by 20% with the G.723.1 codec. Therefore, this technique successfully reduces the bandwidth and channel time of VoIP 5G networks when using the IPv6 protocol.

The header of the Voice Over Internet Protocol (VoIP) packet, which consists of 60-byte RTP/UDP/IPv6 (40-byte IPv6), wasted up to around 85.7% of the bandwidth specified for a VoIP call
VoIP services provide many features that make them extremely wide-reaching in the telecommunication sector
Summary
The technology world is continually changing and developing to advance the current technologies with new services and features that make people’s lives easier, faster, and better. VoIP is wasting a considerable share of the 5G technology bandwidth with no valuable use This condition is due to the lengthy header of the VoIP packet compared with its payload [7,8]. A new method is proposed to enhance the bandwidth utilization of 5G networks when running VoIP on IPv6. The proposed method uses the superfluous fields of the IPv6 protocol to carry the digital voice data of the packet. The proposed method reduces the payload size or makes it zero This condition enhances the bandwidth utilization of the used networks, such as 5G networks.
