PRI (Primary Rate Interface) and SIP (Session Initiation Protocol) are both technologies used for voice communication. PRI is a traditional telecommunication system that uses the ISDN standard to deliver multiple voice lines over a single physical connection, typically through T1 or E1 lines. SIP, on the other hand, is a modern, internet-based protocol that facilitates voice and video calls over IP networks, offering more flexibility and scalability compared to PRI.
