How Does VoIP Service Work?
Summary:
Voice over Internet Protocol (VoIP) is a technology that converts voice signals (analog) into digital signals to be transmitted over the internet. When you connect a standard analog phone to a high-speed internet connection using VoIP, an Analog Telephone Adapter (ATA) is placed between the phone and the computer to facilitate this process.
Understanding the Process:
Making a Call:
1. Initiating the Call: Dial the desired number on your analog phone connected via VoIP.
2. Signal Conversion: The ATA converts the phone’s touch tones into a digital format.
3. Routing the Call: The digital phone number is sent to the VoIP provider’s routing system over the internet. The provider identifies the recipient's location and connects to the Public Switched Telephone Network (PSTN) there.
4. Completing the Call: The recipient’s phone rings, allowing you to begin the conversation. The ATA continually converts your voice from analog to digital packets for transmission over the internet.
Receiving a Call:
1. Voice Conversion: The recipient’s voice data travels through the PSTN and internet, converting from analog to digital.
2. Signal Transmission: These digital packets arrive at your location’s ATA, which reverts them to analog signals. This allows you to hear your caller’s voice clearly.
Technology Behind VoIP:
The conversion between analog and digital signals is possible due to longstanding digital electronic technologies, similar to how PC sound cards convert digital CD audio to analog for speakers. The challenge lies in seamlessly transmitting digital data across the internet and reassembling it in real-time, a process governed by specific protocols. This ensures there are no breaks in the audio stream, maintaining clarity and reliability often on par with or superior to traditional phone networks.
VoIP Equipment:
Today’s VoIP setups can include ATAs for headsets or phones with built-in ATAs, resembling regular analog phones. These devices can connect to computers through high-speed internet or directly to a router, making integration convenient and efficient.
