What is SIP trunking?
SIP trunks are virtual phone lines allowing you to make and receive calls over the internet to anyone with a phone number.

How does SIP trunking work?
SIP trunking sends voice and other communications over the internet through an IP-empowered private branch exchange (PBX), a telephone system inside an enterprise that switches calls between users on local lines while enabling them to share the use of external phone lines.
A PBX decreases costs by avoiding requiring each user to have a string to a telephone company's central office. SIP can be employed to send and receive local and long-distance calls, text messages, and emails; browse the internet, and conduct video chats.
SIP trunking substitutes the traditional method of the public switched telephone network (PSTN), a copper-wire, a circuit-switched network that requires a physical link between two points to make a call. Alternatively, SIP trunks use a packet-switched network, which breaks down voice calls into digital packets and sends them over a network to their target.
SIP vs. VoIP

"VoIP" is a general term that can be explained as any internet-based phone service (including SIP). Nonetheless, SIP is a protocol that allows VoIP by instituting start points and endpoints and defining messages during a call.
