The Quadro4L is the latest solution from Epygi. This product will be replacing the Quadro6L, due to the tremendous customer feedback to add analog station ports to that product. The Quadro4L will offer four (4) FXO ports to access the PSTN for outbound calls. There will be two (2) FXS ports for analog phone connects, and in addition the Quadro4L will offer 16 IP phone support by default. An eight (8) port expansion license can be purchased to increase the IP phone support to 24 phones, bringing the total number of extensions to 26. In Key System Mode, only 12 IP phones can be configured. Please contact your local partner for ordering and availability information.
