What is a Voice PRI Line?
A Primary Rate Interface (PRI) line is an Integrated Services Digital Network (ISDN) line (which is a standard telecommunication phone line), enabling voice, data, and video to be transmitted across a traditional telephone line.
PRI circuits have two pairs of copper lines, terminating on a modem spanning from the service provider to the caller’s business.
A Voice PRI line can process 23 calls, whether incoming or outgoing, simultaneously. PRIs are end-to-end digital circuits providing comparably higher voice quality than analog trunk lines.
