What is a VoIP Server?

What is Voip Server

A VoIP server is a specialized computer system or software application responsible for transferring voice (calls) over the Internet. It lets people make HD-quality voice calls through computers, smartphones, and VoIP phones.

A VoIP server can be software or hardware that transmits real-time calls. It handles various aspects of call routing, signaling, and media processing and ensures good sound quality. Essentially, it keeps the whole VoIP phone system running smoothly.

How does Voice Over Internet Protocol Server work?

Voice over Internet Protocol server works by converting analog audio signals into digital signals and transferring them over a high-speed internet connection.
Here’s how the VoIP server works:

  1. Capture analog audio signal: The VoIP server first takes analog audio (your voice)  when you speak on the VoIP phone.
  2. Convert analog audio signal into digital signal: Your captured voice is converted into a digital data packet using analog-to-digital conversion (ADC).
  3. Traveling over the internet: Then, data packets move to the VoIP provider’s server using an internet connection.
  4. Routing and codecs: VoIP providers find out where to send a call and compress data using codec software.
  5. Convert back to analog signal: Data packets are converted into analog signals using digital-to-analog (DAC) and sent to the receiver.
  6. Hearing to the receiver: Finally, the receiver can listen to your voice. Now, you are having a conversation on VoIP.

Components of VoIP Server

Here are some of the critical components of a VoIP server:

  • Media server: This software application supports voice, video, and additional features such as voicemail, IVR, and voice mail to email.
  • Application server: A computer service that stores and runs software applications, ensuring they work properly according to user demand.
  • Signaling gateway controller: This is responsible for transferring the signaling messages between different networks, one format to another over IP.
  • Softswitch: This is responsible for call routing, control, and signaling. After checking the dialed number, user availability, and network conditions, it directs incoming calls to the correct destination.
  • SIP server: Session Initiation Protocol initiates, maintains, and terminates VoIP calls. It manages SIP signaling between endpoints, helping call setup, teardown, and other call control features.
  • Media gateway: It interfaces between the VoIP network and the regular PSTN. It changes analog signals from a regular phone into digital information that can travel over the Internet and vice versa.
  • Codec: It is used to compress and decompress audio data for efficient transmission over the internet. VoIP servers support various codecs to accommodate different network conditions and bandwidth requirements.
  • Session Border Controller(SBC): They are deployed at the network border to secure and manage the call traffic, ensuring security and QoS.

Why is a VoIP Server necessary?

A VoIP server is necessary because it plays a pivotal role in facilitating voice and video communication over the Internet. It does vital functions such as storing, receiving, and distributing data. 

Plus, it handles all the call routing, connections, and data flow, ensuring your calls go through. It’s also the brains behind those voicemail and call-forwarding features you love.

Without a VoIP server, the establishment of connections and facilitation of communication between users would be impossible.

Different Types of VoIP Servers

There are two types of VoIP servers. They are:

1. SIP Server

SIP Server

An SIP server is a type of VoIP server which manages and controls communication sessions between VoIP users. It is responsible for initiating, maintaining, and terminating real-time communication sessions that include voice, video, and instant messaging. It doesn’t actually handle the voice data but instead sets up the connection between endpoints.

2. PBX Server

PBX Server

PBX servers are private telephone networks used within an organization to manager both inbound and outbound calls. 

A PBX server routes calls within your organization, manages extensions for different users, and offers features like voicemail, auto attendants, and call forwarding. PBX servers can be on-premises or cloud-based and are often integrated with other business applications, such as CRM software.
