Asterisk SIP Trunking is a VoIP (“Voice Over Internet Protocol,” an online system that allows internet calls to take place) service that connects one’s asterisk phone system to their PSTN, or Public Switched Telephone Network.
This is typically used by businesses around the world, but especially in the USA. “SIP” stands for Session Initiation Protocol, which is, of course, a way in which voice calls or video calls are initiated on the internet IP address.
