VoIP Defined

VoIP stands for Voice over Internet Protocol. It’s a technology that converts your voice into a digital signal, so you can make calls from a VoIP phone or computer. Simply put, it’s a way to make calls over the Internet.  

SIP Defined

SIP stands for Session Initiation Protocol which is a protocol that handles the exchange of transmission. It enables voice calls, video chats, meetings, instant messages, and other types of unified communications. Therefore, SIP is a specific protocol that enables VoIP. 

Are SIP and VoIP the Same?

No. VoIP is essentially a phone service delivered through the Internet, while SIP helps manage communication sessions using various aspects of unified communications. Simply put, SIP is used to support and scale VoIP. Because they are two different technologies, VoIP vs. SIP isn’t necessarily a comparison.

VoIP and SIP Explained

SIP and VoIP work together to make and receive phone calls over the Internet, but they are entirely different technologies. For many modern VoIP systems, both VoIP and SIP support are necessary. If you’re looking to improve your business communication and help reduce costs, moving to VoIP with SIP implementation is recommended. SIP enhances basic VoIP capabilities by allowing you to exchange files, videos, and messages rather than just voice alone.
