What is SIP?

How Does a SIP Call Work?

PBX (Private Branch Exchange): your on-premises system that manages both incoming and outgoing phone calls alongside internal interaction in an organization.
PRI (Primary Rate Interface) lines: is an end-to-end digital telecommunication connection with lines connecting calls to the PSTN
PSTN (Public Switched Telephone Network): the network that allows the calls to reach their destination
Generally, IP calling avoids the usage for PRI lines. Where 'Trunking' refers to be the backbone of a phone line, there a ‘SIP trunk’ refers to a phone line that uses the SIP protocol , which is practically installed over your internet connection. It makes use of this internet connection to connect your PBX to the PSTN, avoiding PRI lines.

With the help of this scenario you can make use of the call features like call forwarding, voicemail, auto attendants, etc. without multiple phone lines.
