PRI stands for Primary Rate Interface and SIP stands for Session Initiated Protocol. SIP Trunk is an IP based technology that is based on data bandwidth whereas PRI voice calls are based on TDM(time-division multiplexing) technology and do not rely on data bandwidth.
The price of a SIP trunk could be 30 to 40% less expensive than that of a PRI. PRI costs higher than SIP Trunk because of additional hardware and circuits.
A PRI typically provides a superior QoS than a SIP trunk, which frequently has to share bandwidth with other data sources, since it employs a dedicated connection for voice transmissions.
A SIP line stands for Session Initiation Protocol line. It transports voice conversations through data lines and the Internet in place of traditional telephone lines. It supports Voice over Internet Protocol (VoIP) telephony, which allows calls to be transmitted via data lines.
A PRI line stands for Primary Rate Interface line. In terms of telecommunications, it is a phone line that adheres to the PRI standard. In order to make voice connections, it uses circuit switching and offers a physical connection to the PSTN (Public Switched Telephone Network).
Even though PRI is thought to be quite reliable, weather, vandalism, and decaying infrastructure can all harm the electrical copper cables in a PRI line. Whereas, when included in a fibre-optic network, a SIP trunk provides more redundancy and is extremely resistant to weather and other sorts of damage.
