“…Thus the focus is on delay as a function of packet exchanges rather than server CPU overheads. Kim et al [23] also measured the call setup delay (along with voice quality metrics such as mean option score) of a SIP-based VoIP system implementation which contains both TLS and S-MIME. But it is not clear what the software and hardware used are, or what the call request rate during the measurement is.…”

Securing VoIP is a crucial requirement for its successful adoption. A key component of this is securing the signaling path, which is performed by SIP. Securing SIP is accomplished by using TLS instead of UDP as the transport protocol. However, using TLS for SIP is not yet widespread, perhaps due to concerns about the performance overhead. This paper studies the performance impact of using TLS as a transport protocol for SIP servers. We evaluate the cost of TLS experimentally using a testbed with OpenSIPS, OpenSSL, and Linux running on an Intel-based server. We analyze TLS costs using application, library, and kernel profiling, and use the profiles to illustrate when and how different costs are incurred, such as bulk data encryption, public key encryption, private key decryption, and MAC-based verification. We show that using TLS can reduce performance by up to a factor of 17 compared to the typical case of SIP-over-UDP. The primary factor in determining performance is whether and how TLS connection establishment is performed, due to the heavy costs of RSA operations used for session negotiation. This depends both on how the SIP proxy is deployed (e.g., as an inbound or outbound proxy) and what TLS options are used (e.g., mutual authentication, session reuse). The cost of symmetric key operations such as AES, in contrast, tends to be small.

“…VOIP (VOICE OVER INTERNET PROTOCOL) Teknologi VOIP (Voice Over Internet Protocol) adalah sebuah teknologi melalui panggilan suara merubah data dari format data analog menjadi digital, jaringan tersebut menggunakan Paket-Switch menggunakan tipe jaringan nirkabel [1]. Voip dikenal juga sebagai Internet Telephony,ip telephony atau digital phone proses pengiriman suara menggunakan protokol (IP) sehingga bisa digunakan untuk percakapan jarak jauh melalui media internet, sedangkan penggunaan VOIP dengan jumlah bandwith yang sangat besar bisa dimanfaatkan untuk video conference selain harganya murah juga bisa bersifat global [2,3,4].…”

“…Internet in electronic commerce, IP telephone, IP fax, IP meeting for new applications in such fields as TV, VoIP technology is developed in this case. VoIP (Voice over IP) is a kind of with IP telephone is given priority, and introduced the corresponding value-added business technology [2]. Its biggest advantage is to take full and efficient use of the Internet and global IP interconnection network resources, to provide more, better and more flexible than traditional business multimedia services.…”

Along with the computer technology, network transmission technology and the rapid development of digital signal processing technology, the application of real-time multimedia services based on IP packet networks more and more, including VoIP is a typical multimedia communication based on IP packet network business, has become the hot topics in the study of the current technology. As a network researchers, to research and development of VoIP technology is of great significance. In this paper, the VoIP key technologies were studied, especially the SIP agreement, then put forward and designed a kind of network communication system for smart phones based on VoIP.
