Abstract

ABSTRACT The importance of communication in public life led many demands will be a communications technology that is relatively inexpensive and efficient in its use. Therefore, built a technology called Voice over Internet Protocol (VoIP). Voice over Internet Protocol (VoIP) is a technology that makes remote communication can be done with the internet media. Protocol to build a VoIP network is a method signaling protocols, including H.323 and Session initiation Protocol (SIP). In VoIP, audio is sent to the Internet need to be converted. Codec instrumental in converting from analog to digital and vice versa. Use of the appropriate codec will be able to optimize the performance of VoIP services in H.323 and SIP protocols. To obtain a quality network of data observed by the parameters of Quality of Service (QoS) which includes: jitter, delay and packet loss. This thesis will discuss the performance of VoIP on the network protocols H.323 and SIP with the codec G.723 and G.729A using OPNET Modeler 14.5. Based on simulation results showed the best values obtained from four scenarios for each parameter as follows: In the jitter parameters, the best value is in the scenario with the SIP protocol G.729A codec at 0.00118 μs. On the delay parameters, the best value is in the scenario with the SIP protocol G.729A codec of 60.286 ms. In the packet loss parameters, the best value is in the scenario with the G.723 codec H.323 protocol amounted to 0.0013%. Keywords : VoIP, H.323, SIP, Codec, QoS, Opnet Modeler 14.5
