Whats The Difference Between PBX T1 PRI and VoIP T1 Service?
T1 Lines can be configured for either legacy PBX systems or the newer IP PBX systems. Digital business telephone systems can be based on one of two important technology standards. These are TDM or Time Division Multiplexing vs VoIP or Voice over Internet Protocol. Both are digital standards, as opposed to the analog single line or Key telephone systems found in very small phone systems. Generally, TDM is associated with PBX or Private Branch Exchange systems traditionally found in medium and larger size businesses. VoIP is the newer technology thought to need completely different equipment and more likely chosen for brand new installations. But there is more of an overlap in these technologies than you might think. Advantages of PBX Phone Systems Legacy PBX phone systems are often designed with very specialized hardware and programming chosen for high reliability. The phone sets may be either analog or digital and are individually connected to the PBX system on their own wiring network
