Editing Voice over IP (section)

=== Integration of VoIP in mobile networks ===
VoIP technology has been adapted for use in [[Cellular network|mobile networks]], leading to the development of advanced systems designed to support voice communication over modern data infrastructures. Among these are Voice over LTE ([[VoLTE]]) and Voice over 5G ([[Vo5G]]), which enable voice communication over IP-based mobile infrastructures. In contrast to traditional VoIP services, which often function independently of global telephone numbering systems, VoLTE and Vo5G are directly connected to [[mobile operator]]s' infrastructures, providing seamless connectivity to the international telephone network.<ref>{{Cite web |last=Wright |first=Arol |date=2023-10-12 |title=What Is Vo5G (VoNR) and How Does It Compare to VoLTE? |url=https://www.makeuseof.com/what-is-vo5g-vonr/ |access-date=2024-11-30 |website=MUO |language=en}}</ref><ref>{{Cite web |title=Communication services (VoLTE/VoNR) |url=https://www.3gpp.org/technologies/volte-vonr |access-date=2024-11-30 |website=www.3gpp.org}}</ref>

VoLTE, introduced as part of [[4G]] [[LTE (telecommunication)|LTE]] networks, enables voice communication over an IP-based infrastructure initially developed for data transmission. It offers features such as high-definition voice ([[HD Voice]]) and faster call setup times compared to [[Circuit-switched network|circuit-switched networks]].<ref>{{Cite web |title=What is Voice Over LTE (VoLTE)?

Vo5G, the [[5G]] equivalent of VoLTE, utilizes the increased speed, reduced latency, and greater capacity of 5G networks to further enhance these capabilities.<ref>{{Cite web |title=What Is 5G VoNR {{!}} Unveiling the Future of Wireless Communication |url=https://www.voicenter.com/blog/5g-VoNR |access-date=2024-11-30 |website=www.voicenter.com |language=en}}</ref> Both VoLTE and Vo5G maintain compatibility with traditional [[public switched telephone network]]s (PSTNs), allowing users to make and receive calls to and from any [[telephone number]] worldwide.

These technologies differ from standalone VoIP services by being fully integrated with mobile network operators. This integration ensures additional features such as [[emergency call]] support and [[quality-of-service]] guarantees, making them a central part of modern mobile telecommunication systems.
