What’s the difference between SIP trunks and PRI trunks?

Primary rate interface (PRI) and SIP trunking are two different ways of connecting your business to the PSTN (Public Switched Telephone Network).

SIP trunks are virtual connections that can handle both voice and data transmissions. SIP trunks require little or no hardware investment for deployment.

Traditional PRI systems are physical connections over a dedicated line which can only handle voice transmission and require complex setup, maintenance and up-front investment in hardware.
