Abstract—In this research, we propose to implement Secure Real Time Transport Protocol (SRTP) on VoIP services in campus environment. Today, the deployment of VoIP in campus environment over wired is not considered on security during communication between two parties. Therefore, this study is to analyzed SRTP performance on different VoIP codec selection over wired. We have implemented a real VoIP network in University of Kuala Lumpur (UniKL), Malaysia.We use soft phone as our medium communication between two parties in campus environment. The results show that implementation of SRTP is able to improve the VoIP quality between one-to-one conversation compare to many-to-many conversation (multi conference call). In our experiment, its hows that G.711, G.726 and GSM codec are able to improve the multi conference (many-to-many) VoIP quality during conversation. In additional, implementation of SRTP on iLBC and SPEEX codec will decrease the multi conference (many-to-many) VoIP quality.
