What is VoIP

What is VoIP

A brief introduction to Voice over Internet Protocol (VoIP).

Voice over Internet Protocol or VoIP refers to the technology that allows us to make and receive phone calls over the Internet in real time. It is a set of protocols working together to deliver internet telephony functions similar to regular phone lines or PSTN. The difference is that it provides flexibility and mobility that is not possible with traditional telephony. By delivering voice calling functions over the Internet, it allows anyone to use VoIP from anywhere via their laptops, desktops, or smart devices.

A virtual phone service for business.

eTollfree VoIP is part of a secure and reliable virtual phone service that also leverages cloud PBX technology. Aside from voice calls, you also get online meetings, SMS, team messaging, and advanced call management features that can help your organization communicate better. More than just a replacement for traditional landlines, eTollfree offers a complete cloud communications platform.

What are the advantages and disadvantages of VoIP and virtual phone services against traditional telephony?

Traditional phone services

  • Traditional phone services
  • No free calls-long distance and international calls are costly and paid per minute.

  • Requires additional physical cable lines for expansion.

VoIP Basics: Important terms and concepts

VoIP is a set of protocols working together to provide telephony service that’s similar to regular landlines.

Before we go over the end-to-end process of how VoIP works, it is important that you familiarize yourself with some basic concepts that will help you understand how the technology works as a whole.

IP Packets for VoIP Transmission

Voice and data are encapsulated here. During a VoIP call, the voice or audio is captured and segmented into tiny samples which are then carried as payloads. These samples are attached to IP packets that will be transmitted between different networks, both public and private.

Codecs for conversion of analog voice data

Also known as codec-decoder, it converts analog audio signals (like your voice) into digital formats that are ready to be transmitted over the Internet. It also converts the digital form back to analog for the human ear.

Transmission Control Protocol (TCP) vs. User Datagram Protocol (UDP) for VoIP delivery

These are the two most common methods for delivering VoIP protocols over the Internet.

  • TCP-IP: packets sent using this method guarantees that data is delivered; and if it’s lost, it will be transmitted. Think quality over speed.
  • UDP-IP: packets are sent over the networks with no guarantee it will be received. Think speed over quality.

Real-time Transport Protocol (RTP) for carrying VoIP audio stream

This protocol is responsible for carrying audio and video streams during VoIP transmissions. It carries the information about the file, including its format and media type.

Session Initiated Protocol (SIP) and SIP Servers for VoIP signaling

SIP is the protocol that is responsible for mimicking regular telephony. It is a standard signaling protocol that establishes, manages, and terminates real-time communications over IP networks.

SIP servers, on the other hand, accept SIP requests and respond to them. There are many types of SIP servers, with the Proxy server being the most known (since it facilitates connections to establish VoIP). Other SIP servers include Registration Server, Presence Server, and Redirect Server.

End-to-end process of VoIP

Using what we learned, here is an example of how a VoIP Call works, with each step showing what is going on in the background for every action taken.

  1. Person A calls Person B (the calling party uses the SIP signal to try to establish a connection via the Proxy server–eTollfree uses TCP to deliver SIP)
  2. Person B answers the call (the called party accepts the request from Proxy Server using SIP)
  3. Person A and Person B talk (IP packet containing Voice data is delivered in via UDP or TCP; RTP transmits the voice data, while Codecs convert analog voice to digital format and vice-versa. All these are happening in real-time.)
  4. Person A or Person B ends the call (the SIP signal is used to terminate the connection)

Making VoIP calls to regular lines or PSTN through VoIP gateways

VoIP gateways are used to convert traditional telephony connections into VoIP connections and vice-versa.

What happens is that when calls are initiated from a traditional landline, the gateway will translate the multiplexed voice into packetized voice sample. It will then follow the same VoIP call process discussed above.

While there’s more to VoIP transmissions than what is discussed here, this should give you a general idea of how VoIP works.

Looking beyond the price

While cost is always a factor when considering a provider or supplier, it should not be the be-all and end-all of your decision making.

Take VoIP providers, for example. If you choose the cheapest provider for your business communications, there’s a good chance that you will also get the cheapest call quality.

In the end, it can lead to lost customers which will eventually lead to lost money.

That is why it is important to look at each offering to see if they are worth the price they are charging.

To help you out, here are some factors you should consider when choosing a VoIP provider:

Security and Reliability

The first thing you should consider when choosing a VoIP provider is security and reliability. Would they be able to keep the service up at all times? Would they be able to protect your calls and other data during transmissions?

RingCentral hosts its virtual phone system in multiple data centers to ensure redundancy and keep their service up at all times. It also employs several security measures like encryption, data center audits, multi-factor authentication, and advanced account administration to protect the system and its users.

Features included

Most VoIP services for business are attached to a more comprehensive phone system, which is equipped with different call management features to help you manage your calls. In some cases, providers require their subscribers to pay extra for premium features to be included in their packages.

RingCentral, though, offers more than that. It not only provides a business phone system for calling and managing incoming calls, but actually provides a unified communications service that also includes team collaboration and HD video meetings in one platform with no separate billings.

Customer Support

Most think of customer support as something that happens when something went wrong. While that is true, customer support is more than that.

Customer support is about assisting customers not only when there is something wrong, but also to prevent major issues. That is why true customer service starts when a customer subscribes.

RingCentral is with you from day one, assisting you in setting up and configuring the system to your own network. After which, its award-winning customer service is available for technical support, consultations, and best-practice recommendations.

Trust indicators

A good VoIP provider will have a reputation for excellent service. To evaluate this, you can look at trust indicators like positive reviews of the company.

RingCentral, as the industry leader in cloud communications, is trusted by more than 350,000 businesses across the country. You can look at the different success stories through testimonials and case studies from actual businesses.

There is more to choosing a VoIP provider than just looking at price. Look at these factors first and see if they are worth the price of their plans and pricing.
