Performance evaluation of VoC network through DNS server

The VoC network through DNS server makes users to be based on a web server, facilitates users to carry out a VoIP registration, to get and to change an account, and also to see others who have been registered and are active in this VoC network. The infrastructure of VoC network uses asterisk as a VoIP server and playVoIP as a web server interface, which programs are included in a server VoC. The VoC server is interconnected to several servers, that is a DNS server, an ENUM server, an access point, a softphone and a smartphone. The VoC network serves clients locally, after that it will be developed so that it could serve in a public network, and furthermore the VoC network could be connected to VoIP Rakyat, the biggest VoIP network in Indonesia. The VoC network has been tested for several QoS parameters, such as delay, jitter, packet loss, throughput and MOS. Average value for each parameter is :19.9 ms delay, 0.025 ms jitter, 0.04% packet loss, 43.6 kbps throughput and 4.2 MOS. Those results indicate that the VoC network through DNS server has a very good performance.
