Dengan bertelepon menggunakan Voip, banyak keuntungan yang dapat diambil. Diantaranya adalah dari segi biaya, jelas lebih murah dari tarif telepon tradisional, karena jaringan IP bersifat global sehingga untuk hubungan Internasional dapat ditekan hingga 70%. Selain itu, biaya maintenance dapat di tekan karena voice dan data network terpisah, sehingga IP Phone dapat ditambah, dipindah dan di ubah. Hal ini karena Voip dapat dipasang di sembarang ethernet dan IP address, tidak seperti telepon tradisional yang harus mempunyai port tersendiri di Sentral atau PBX.
Hal yang menarik tentang VoIP adalah banyaknya cara untuk melakukan panggilan. Saat ini ada 3 jenis metode yg berbeda yang paling sering digunakan untuk melakukan layalan Voip, yaitu :
1. ATA (Analog Telephone Adaptor)
Cara yang paling sederhana dan paling umum adalah dengan menggunakan suatu alat yang disebut ATA. ATA memungkinkan kita untuk menghubungkan pesawat telepon biasa ke komputer atau disambungkan ke internet untuk dipakai Voip. ATA adalah alat pengubah sinyal dari analog menjadi digital. Cara kerjanya adalah mengubah sinyal analog dari telepon dan mengubahnya menjadi data digital untuk di transmisikan melalui internet. Provider seperti VONAGE dan AT&T Callvantage membuat alat ATA dan memberikannya secara gratis kepada pelanggannya sebagai bagian dari service mereka. Mereka tinggal membuka ATA, memasang kabel telepon ke alat, dan Voip sudah bisa digunakan. Beberapa jenis ATA dipaket dan dibundel beserta software tambahan yang harus diinstalkan pada komputer untuk melakukan konfigurasi ATA, tetapi pada umumnya itu hanya setting yang sangat gampang.
2. IP Phones
Pesawat telepon khusus ini kelihatannya sama dengan telepon biasa. Tapi selain mempunyai konektor RJ-11 standar, IP Phones juga mempunyai konektor RJ-45. IP Phones menghubungkan langsung dari telepon ke router, dan didalam IP Phones sudah ada semua perangkat keras maupun lunak yang sudah terpasang didalamnya yang menunjang melakukan pemanggilan IP. Tidak lama lagi, IP Phone nirkabel (wireless) akan tersedia, dan memungkinkan para pengguna untuk melakukan panggilan Voip dari hotspot yang tersedia.
3. Computer-to-Computer
Cara ini jelas merupakan cara paling mudah untuk melakukan panggilan Voip. Anda bahkan tidak usah membayar satu sen pun untuk melakukan panggilan SLJJ. Ada beberapa perusahaan yang menawarkan program yang harganya murah bahkan gratis yang dapat digunakan untuk melakukan panggilan Voip. Yang harus anda sediakan hanya program (software), mikrofon, speaker, soundcard dan koneksi internet, lebih diutamakan koneksi internet yang relatif cepat seperti koneksi Kabel atau DSL. Selain biaya bulanan ISP, biasanya tidak ada lagi biaya untuk panggilan Computer-to-Computer, seberapa jauh pun jaraknya.
