Question 1

How does VoIP / Cloud Voice work?

Ervina Sokoli · Accepted Answer

The biggest difference between traditional and cloud-based phone systems is the way your calls are transmitted. Instead of travelling through underground copper cables, calls are transmitted over the internet. In traditional analogue systems, phones are connected to one another via the PSTN (Public Switched Telephone Network). nnVoIP (Voice over Internet Protocol) or cloud voice refers to the technology and infrastructure that allows voice communication over the internet instead of traditional phone lines. It converts analogue audio signals into digital data and transmits it over an IP network, such as the internet, enabling voice communication between users. Here's a simplified explanation of how VoIP or cloud voice works:n- Voice Digitization: When you speak into a microphone or handset, the analogue audio signals are converted into digital data. This process is known as voice digitization or encoding. The analogue-to-digital conversion samples the audio at regular intervals, measures the amplitude (loudness) of the signal, and assigns a binary value to represent that amplitude.n- Packetization: The digitized voice data is divided into small packets for transmission. Each packet typically contains a portion of the audio data, along with header information that includes the source and destination IP addresses, sequencing information, and error correction data.n- IP Network Transmission: The voice packets are transmitted over an IP network, such as the internet, using Internet Protocol (IP). The packets travel across the network independently and may take different routes to reach the destination.n- Routing and Switching: Routers and switches on the IP network direct the voice packets towards their destination based on IP addresses and routing protocols. They make decisions on the most efficient path for packet delivery, taking into account factors such as network congestion, latency, and available bandwidth.n- Packet Loss and Jitter: During transmission, some voice packets may encounter delays, packet loss, or out-of-order delivery due to network conditions. These issues can lead to degraded call quality or interruptions. To mitigate these problems, various techniques like buffering, error correction, and jitter buffering are used to compensate for packet loss and delays.n- Destination Reception: The receiving end of the call collects the voice packets and reassembles them in the correct order. The digital data is then converted back into analogue audio signals using a process called decoding or voice synthesis.n- Voice Playback: The analogue audio signals are played through a speaker or headset, allowing the recipient to hear the voice communication.n- VoIP or cloud voice technology offers several advantages over traditional phone systems, including cost savings, flexibility, scalability, and integration with other communication and collaboration tools. However, it's important to note that the quality and reliability of VoIP calls can be influenced by factors such as network conditions, bandwidth availability, and the quality of the VoIP service provider's infrastructure.
