The Polycom Vortex EF2201 is a DSP-based telephone interface designed to seamlessly add analog phone line connectivity to installed conferencing systems, particularly those using other Polycom Vortex products. It serves as a digital hybrid, connecting outside callers to a meeting via a standard analog (PSTN) telephone line. The device significantly reduces background noise on the phone line and uses a digital expansion bus for integration with other Vortex 2200 series products, eliminating the need for analog inputs or outputs.
