Nex-G Innovations

The objective of the Voice Over IP (VoIP) and Session Initiation Protocol (SIP) training program is to provide participants with a thorough understanding of VoIP technology and SIP protocols, focusing on their architecture, functionality, and integration. The training aims to equip learners with the skills to design, configure, deploy, and troubleshoot VoIP systems using SIP for efficient and secure communication networks.

Through hands-on labs and real-world scenarios, participants will gain expertise in SIP trunking, call flow management, VoIP security, and Quality of Service (QoS) optimization, preparing them to implement and manage robust VoIP solutions in diverse environments.
