PRI (Primary Rate Interface) combines local and long distance phone service into a communications package for businesses with high call volumes. Its features include local service, 40 direct-dial numbers, caller ID, flat rate local and local-toll usage, low long distance rates, and more. With PRI, you can eliminate the need for a receptionist or auto attendant by enabling your employees. You’ll also improve customer service by identifying callers by name and doing away with busy signals.
