Phone calls are still a vital tool for communications nowadays. Professional businessmen use a different method in conversation. You can still find a regular employee to depend on the phone, either by email or call, chat, video conferencing, and text. However, our recent advancement in technology makes it possible to expand communications for businesses. 

The way we communicate every day has revolutionized both VoIP and SIP technologies, although it is a fact that most of us are not fully aware of these two methods of global voice communications. An industry expert might notice the differences between the two, but for most amateurs, they may seem unnoticeable. 

Both VoIP and SIP provide internet-based options to the traditional way of the telephone system. Even though we might find that they both share a few important similarities, it is also worthy to know the key differences between the two. 


What Are SIP and VoIP? 

Understanding the differences between the two will significantly allow you to rightly choose whether SIP or VoIP or both of them are needed for your business. An in-depth understanding will help you decide which cloud-based technologies best for you and your business. 


VoIP (Voice over Internet Protocol) 

VoIP simply means any technology that permits voice signals to transmit over the Internet. Also called IP telephony, VoIP phone system uses the Internet instead of the traditional phone lines. With VoIP, a user can make a call using a computer, or a VoIP phone. 

It is an important thing to note that VoIP is a voice service, which is noticeably the main difference against SIP. And to make it simpler, VoIP is a technology that allows you to make or receive calls using data connectivity. 


SIP (Session Initiation Protocol) 

SIP, on the other hand, refers to a communications protocol that can convey all forms of media, and not limited to voice messages only. It can carry all structures of media that include voice, data, and video. Companies that rely heavily on multimedia communications highly preferred SIP technology over VoIP. 


Key Differences between VoIP and SIP 

  • VoIP simply means placing or receiving voice calls using Internet data connectivity. While SIP can convey all forms of media communications and not just limited to voice calls. 
  • VoIP capacity is limited to sending voice messages only. Whereas SIP, through the transmission via data networks, is widely used for multimedia communications since it can carry voice calls, video conferencing or calls, instant messaging, and other media distribution. 
  • VoIP, as mentioned earlier, is an effective alternative to traditional telephone lines since it utilizes the Internet in making and receiving calls. SIP is a coding rule system and is a text-based protocol. This might sound too technical for the average individual but a deeper knowledge of how SIP works would be a helpful benefit. Since SIP is a text-based protocol that uses the Unicode Transformation Format (UTF), SIP providers allow their clients to either initiate, deliver, or terminate real-time communications over the Internet. That is why SIP is capable of supporting voice, instant messaging, and video. 
  • As mentioned, VoIP supports voice communications between single parties. While SIP supports a broader set of the application process since it supports multimedia communication between multiple parties. 
  • Also called IP telephony or Internet telephony, VoIP solely refers to technology that allows for a call to be conveyed via the Internet. SIP is a type of protocol that enhances VoIP into a media communications experience. By saying this, it only means that without SIP, a VoIP service is limited to voice-only Internet phone service. 

As you see, there is no direct comparison with VoIP versus SIP. It would be more appropriate to tackle VoIP with or without SIP. And to make the most out of this information, it is worthy for you to ask yourself what type of communication is needed for your business.  

If you are content to use voice communications only, it would be worthwhile to consider VoIP without SIP. However, if you do have a plan to level up your business along with your communication set up, it would be much better to choose VoIP with a SIP application because you can incorporate all the features that come with this choice. Think of the fact that in today’s business communication, voice calls alone are not enough to bring your business one step ahead. 

 Despite the differences between the two, VoIP and SIP work together perfectly. A good example of this is softphones. Sometimes called as SIP phones because they use SIP, they connect devices to VoIP networks. Once done, a softphone is integrated with a single phone number in which a user can employ within multiple devices. Softphones that were associated via cloud-based network-free phone numbers from limitation to a single device. So far, this is the most striking difference between VoIP-enabled phones and traditional landlines. 

When Sip and VoIP work together, they can provide your business with a clear advantage over other competitors. It will give you an edge over others since a SIP enhanced VoIP does not only unify your business communication, but it is also a very effective way of saving money and productivity gains as well. 

VoIP enhanced with SIP is the most flexible answer to all your communication needs. It opens the door for further scaling up your business with the help of its useful functionalities. However, it would still depend on certain factors that include the following: 

  • Your budget and resources that should be put into consideration 
  • What your business needs and other related requirements 
  • Availability of your in-house experts such as IT support
  • Short-term or long-term consideration that would depend on how you scale up your business.
