Description

Overview

DAG3000-24O is a multi-functional analog gateway offering seamless connectivity between IP-based telephony networks and legacy telephones (POTS), and PBX systems. It adopts modularized hardware design that allows to expand FXO ports by adding boards according to user’s requirements. Each board has 8 FXO ports and the gateway supports 24 FXO ports at maximum.

DAG3000-24O supports the standard SIP protocol and it’s compatible with leading IMS/NGN platforms and SIP based IP telephony systems. Which is ideally suited for small and medium businesses, call centers and multi location environments that need VoIP services.
