FXS Gateway — Connect Analog Phones to IP PBX

DAG1000 Series (2–8 FXS): Compact desktop gateways for small offices. Connect 2 to 8 analog phones, fax machines, or paging systems to your IP PBX. Gigabit Ethernet models (GE) available for high-throughput environments.

DAG2000 Series (16–32 FXS): 1U rack-mount gateways for medium businesses. Hot-swappable design with 16, 24, or 32 FXS ports. Ideal for floor-by-floor analog phone migration.

DAG2500 (48–96 FXS): High-density gateway for large analog deployments. Configurable 48, 72, or 96 FXS ports in a single chassis.

DAG3000-312S: Carrier-grade gateway with 312 FXS ports. For service providers and large enterprises migrating hundreds of analog endpoints simultaneously.

FXO Gateway — Connect PSTN Lines to IP PBX

DAG1000 FXO (2–8 ports): Connect 2 to 8 PSTN analog trunk lines to your IP PBX. PSTN-to-SIP conversion with automatic failover — if VoIP goes down, calls route through PSTN automatically.

DAG2000-16O (16 ports): 1U rack-mount with 16 FXO ports for organizations with many PSTN lines. Caller ID detection, polarity reversal, and disconnect supervision.

Hybrid Gateway — FXS + FXO in One Device

DAG1000 Hybrid (1S1O to 4S4O): Compact gateways combining FXS and FXO ports. Connect analog phones AND PSTN trunk lines in a single device. Power failover ensures emergency calls work even during power outage.

DAG2000-8S8O: 1U rack with 8 FXS + 8 FXO ports. Perfect for branch offices that need both analog phone support and PSTN backup.

DAG3000-32S/O: 32 ports configurable as any mix of FXS and FXO. Maximum flexibility for complex analog migration projects.

Why Dinstar for Analog Migration

Cost-effective: Dinstar gateways cost 30–50% less than Yeastar or Cisco equivalents while delivering the same SIP compatibility and voice quality. Ideal for large-port-count deployments where cost per port matters.

Wide compatibility: Tested and certified with Yeastar P-Series, 3CX, Asterisk, FreeSWITCH, Cisco CUCM, Avaya, and BroadSoft. SIPPER pre-configures every gateway before delivery.

Business continuity: Power failover (FXS to PSTN bypass), SIP failover (backup SIP server), and PSTN failover (route via analog if VoIP fails) — triple protection for critical voice services.
