SIP, Layanan keamanan, Performansi Pensinyalan, Kualitas PanggilanAbstrak
Dalam aplikasi SIP-Based VoIP, dua end point / User Agent (UA)
dapat berkomunikasi secara peer to peer / peering menggunakan SIP,
begitu juga interkoneksi antar SIP server sehingga implementasi SIPBased
VoIP tidak hanya dapat diterapkan untuk jaringan akses, namun
juga interkoneksi antar operator melalui jaringan IP. Penelitian ini
mencoba memberikan analisa interkoneksi antar operator untuk
International Direct Dialing (IDD) yang diterapkan di internasional
switching center PT. Indosat, Tbk. menggunakan protokol SIP yang
mencakup mekanisme layanan keamanan (security service), performansi
pensinyalan SIP dan kualitas panggilan. Layanan keamanan mencegah
terjadinya kemungkinan serangan DOS dari jaringan luar. Performansi
pensinyalan setelah adanya layanan keamanan menunjukan performa
yang sangat baik SEER 99.6% untuk incoming dan 98.94% untuk
outgoing, SER sebesar 22.68 % untuk incoming dan 47.11% untuk
outgoing. Kinerja kualitas panggilan dengan perspektif penilaian
pengguna (end user), menggunakan parameter MOS didapatkan nilai 4.4
dan R-Factor diantara 93-93.2 setiap jam.
