Analysis QoS VoIP using GRE + IPSec Tunnel and IPIP Based on Session Initiation Protocol

The development of communication technology is now very dependent on the internet, not only for information delivery but also for telecommunications (Voice and Data). VoIP (Voice over Internet Protocol) is a communication technology based on IP (Internet Protocol). Data confidentiality using a VPN (Virtual Private Network) can remote access from a private network to another private network over the internet and use protocol tunneling in its security system. The method used in this study is the PPDIOO method (prepare, plan, design, implement, operate, optimize). This method was chosen because it contains the right elements to use in the research. The results of the application of this method will later produce conclusions such as the quality of VoIP using private servers by comparing between GRE tunnel + IPSec and IPIP tunnel on the Internet network. Testing is done between sites with Voice calls. So that quality of service analysis is obtained with delay, jitter, throughput and packet loss parameters. The test results of the Quality of Service of VoIP communication running on intranet networks by utilizing the IPIP tunneling method are better than using the GRE + IPSec tunneling method.
