What is SIP Trunking & How Does It Work?
Session Initiation Protocol (SIP) Trunking is a modern communication technology that facilitates the transmission of voice, video, and other multimedia services over the internet.
Instead of relying on traditional phone lines, SIP Trunking uses the internet to establish and manage communication sessions.
It converts voice signals into data packets, which are then transmitted over the internet to their destination.
What is VoIP
& how does it work?
VoIP is an acronym for a Voice over Internet Protocol, technology that converts your voice into digital data packets. Those are then transmitted over the internet, with no need for traditional phone lines. Once the data packets arrive at a recipient's end, they transform back into voice signals.
VoIP software is cost-effective, scalable, and offers a wide range of features. If you are seeking an efficient and affordable communication solution, it's a great choice.
