What is ISDN PRI? This acronym stands for Integrated Services Digital Network, Primary Rate Interface and is sometimes hyphenated so it looks like: ISDN-PRI. Basically, ISDN PRI is a telecommunications protocol that enables both voice and data to simultaneously run over a traditional telephone line and IP/PBX phone system. ISDN PRI Lines are beneficial on several levels including added cost-savings, 100% digital clarity and features including caller ID that are not found with traditional phone lines. ISDN PRI is ideal for small to mid-sized businesses with eight or more employees.
