Rancang Bangun Dan Analisa Quality Of Services (QoS) VoIP Server Menggunakan Briker Dengan Memanfaatkan Trunk Dan Interactive Voice Respons (IVR) Di AirNav Padang

In the digital era, VoIP communication technology is popular due to its low cost and good voicequality. At the AirNav Padang, communication is still manual using conventional telephones, which isconsidered expensive and less effective. The solution is to implement VoIP through the local network, utilizingcomputers, smartphones, headphones, and analog phones for cost efficiency and cross-divisioncommunication. Similar research has addressed cost issues with VoIP. However, VoIP implementationrequires good Quality of Service (QoS) to avoid delays, jitter, and packet loss that can disrupt communication.This research focuses on the design and analysis of QoS for a VoIP server with Briker, trunk, and IVR at thePerum LPPNPI Padang Branch Subsidiary Office. QoS measurements show an average delay of around22.754 ms, an average jitter of about 3.572 ms, and an average packet loss of about 0.04% for calls betweenclients. Meanwhile, for calls with trunk and IVR, the average delay is approximately 21.756 ms, the averagejitter is around 5.402 ms, and the average packet loss is about 0.05%. This solution can optimize cross-divisioncommunication with low costs and high efficiency.Dalam era digital, teknologi komunikasi VoIP populer karena biaya rendah dan kualitas suara yangbaik. Di Perum AirNav Padang, komunikasi yang dilakukan masih manual dengan telepon konvensionalsehingga dinilai mahal dan kurang efektif. Solusinya adalah menerapkan VoIP melalui jaringan lokal,memanfaatkan komputer, smartphone, headphone, dan telepon analog untuk efisiensi biaya dan komunikasilintas divisi. Penelitian serupa telah mengatasi masalah biaya dengan VoIP. Namun, implementasi VoIPmemerlukan Quality of Service (QoS) yang baik untuk menghindari delay, jitter, dan packet loss yangmengganggu. Penelitian ini fokus pada perancangan dan analisis QoS VoIP server dengan Briker, trunk, danIVR di Perum LPPNPI Cabang Pembantu Padang. Pengukuran QoS menunjukkan nilai rata-rata delay sekitar22.754 ms, jitter rata-rata sekitar 3.572 ms, dan packet loss rata-rata sekitar 0.04% untuk panggilan antar client.Sedangkan untuk panggilan dengan trunk dan IVR, nilai rata-rata delay sekitar 21.756 ms, jitter rata-ratasekitar 5.402 ms, dan packet loss rata-rata sekitar 0.05%. Solusi ini dapat mengoptimalkan komunikasi lintasdivisi dengan biaya rendah dan efisiensi tinggi
