In recent years we’ve seen one country after another make the switch from PSTN / copper lines to ISDN lines – meaning that telecommunications are done entirely online. The technology used to make this happen is VoIP (Voice over Internet IP) along with SIP Trunks (Session Initiation Protocol).
We’ve put together a list of the most common questions we come across when businesses decide or are forced to make the switch from their traditional phone lines to VoIP. Hopefully, these will help you understand how SIP Trunks work and how you can effortlessly make the transition.
What are SIP Trunks?
SIP is an acronym for Session Initiation Protocol and it’s a way to make end-to-end data transmission (voice and video) over the internet. A SIP trunk is a link between your PBX and PSTN using an internet connection.
What’s the difference between SIP and VoIP?
VoIP is the technology used to make and receive phone calls either over the internet or in an internal network. SIP is mainly used to support IP Technology (such as VoIP) and is an application layer protocol used to make and receive multimedia sessions (voice, video, messages etc.).
What are the requirements for a SIP Trunk?
To get your own SIP Trunk all you need is a reliable broadband connection, a PBX and a trustworthy SIP Trunk Provider.
What is a SIP Channel?
A SIP channel is the virtual version of a telephone line. The number of channels you need depends on the number of concurrent calls or users you have.
