SIP Trunking vs VoIP: What’s the Difference? 

SIP TrunkingDespite what many people think, SIP (Session Initiation Protocol) Trunking and VoIP (Voice over Internet Protocol) are not the same thing. However, they are related. If you understand the differences between the two, your business has the opportunity to harness the benefits of them both. Using them with your Business Phone System can save your business a lot of money and let you gain access to advanced telephony functionality. 


VoIP is a technology that allows you to send and receive voice calls over your Internet connection. SIP Trunking is a protocol used in VoIP. More specifically, VoIP can replace your traditional phone lines by using the internet. This offers significant cost savings and more features. SIP Trunking is one of many protocols you can use in VoIP. It is by far the most popular choice. SIP Trunks are essentially virtual phone lines that support more than phone calls; you can also use SIP Trunks for messaging, video conferencing, and media transferring.
