Anatomy Of a Typical Voip Call (part one)

Have you wondered how a typical voip call happens? Here is part one of a basic voip call anatomy.

Anatomy Of a Typical Voip Call

Like a PSTN Phone call, every voip call has a beginning, a process and a termination point. Voip sessions start in any to three ways: They can be initiated oer a PSTN device/phone, a PC, or with a SIP Phone.

Placing a VoIP call using a PSTN or regular phone is no different from making a traditional phone call, except that the call is passed or routed through an Analog Telephone Adapter (ATA).

You see, the Internet is a digital world and those who wish to play, must play on a digital plan field. For that reason, your analog voice signal from your regular phone device, must be transformed into a digital format before being sent over the digital playing field of the Internet.

The job of converting your analog voice signal falls in the purview of your Analog Telephone Adapter (ATA).
