What is SIP Trunking?
SIP Trunking is a modern technology that allows businesses to make calls using VoIP (Voice over Internet Protocol). It enables businesses to make and receive calls over the Internet. SIP Trunk is made up of two words: “Trunk” which refers to a group of phone lines, and “SIP” (Session Initiation Protocol), which is known for enabling calls over the internet. With SIP Trunk, businesses can make and receive calls, conduct video conferences, and exchange data, group meetings, send personal data all through an internet connection.
