Voip Gateway

Voip Gateway Wellgate-2540 4 FXO

Pengertian Voip Gateway :

Voip singkatan dari Voice Over Internet Protocol. Voip adalah Teknologi yang menjadikan media internet untuk bisa melakukan komunikasi suara jarak jauh secara langsung. Sinyal suara analog, seperti yang anda dengan ketika berkomunikasi di telepon diubah menjadi data digital dan dikirimkan melalui jaringan berupa paket - paket data secara real time.

Fungsi Voip Gateway :

Menyediakan FXO atau FXS. Tapi, bisa dikoneksikan ke internet atau intranet.

Kelebihan Voip Gateway :

1. Biaya yang rendah untuk sambungan langsung jarak jauh. Karena penekanan utama dari Voip adalah biaya.Untuk dua lokasi yang terhubung dengan internet maka biaya percakapan menjadi sangat rendah.
2. Memanfaatkan infrastruktur jaringan perusahaan sudah ada untuk suara. Bagi perusahaan yang sudah mempunyai infrastruktur jaringan. Jika memungkinkan jaringan yang ada bisa dibangun jaringan Voip dengan mudah. Karena tidak diperlukan tambahan biaya bulanan untuk penambahan komunikasi suara Voip.

Kelemahan Voip Gateway :

1. Kualitas suara tidak sejernih Telkom.
2. Ada jeda dalam berkomunikasi
3. Regulasi dari pemerintah RI membatasi penggunaan untuk disambung ke jaringan milik Telkom.
4. Peralatan relatif mahal.

J    Prinsip Kerja Voip :

     

     Prinsip Kerja Voip adalah mengubah suara analog yang di dapatkan dari speaker pada komputer menjadi paket data digital, kemudian dari PC diteruskan melalui Hub/Router/ADSL Modem dikirimkan melalui jaringan internet dan akan diterima oleh tempat tujuan melalui media yang sama. Atau bisa juga melalui media telepon diteruskan ke phone adapter yang disambungkan ke internet dan bisa diterima oleh telepon tujuan.
