IP Voice Gateway AUDIOCODES MP1288-72S-2AC with 72 FXS ports, dual AC power

AUDIOCODES MP1288-72S-2AC is an IP voice gateway that provides 72 FXS ports and dual AC power for stable analog-to-VoIP connectivity. Intended for service providers and enterprise telephony environments, the gateway enables integration of analog phones, fax machines and legacy PBX lines into IP networks. The device supports high-density port consolidation, call routing and media conversion to simplify migration and expand voice infrastructure without replacing existing analog equipment.

Advantages

The gateway consolidates a large number of FXS interfaces into a single chassis, reducing rack space and management overhead. Dual AC power supplies provide redundant power for increased availability. Designed for professional telephony use, the device offers reliable media conversion and interoperability with SIP-based networks and common PBX platforms. Its high port density and centralized management capabilities help lower total cost of ownership for multi-site and branch deployments.

Suitable for

• Integrating analog phones and fax devices into VoIP networks
• Branch office telephony and remote site deployments
• PBX migration projects where legacy equipment must be preserved
• Service provider access and last-mile voice consolidation
• Large-scale voice infrastructure requiring high port density

Key specifications

• Port type and quantity: 72 FXS ports for analog end-points
• Power: dual AC power supply for redundancy
• Form factor: high-density chassis suitable for rack mounting
• Network interfaces: Ethernet connectivity for SIP/VoIP transport
• Media handling: call routing, transcoding support and media conversion
• Management: centralized configuration and monitoring via standard management interfaces

How to use

Install the gateway in a standard equipment rack and connect both AC power inputs for redundancy. Connect the analog devices to the FXS ports and attach the gateway to the IP network using the Ethernet interface. Configure SIP trunking, call routing and device provisioning through the management interface according to the telephony architecture. Verify dial plan, codecs and fax settings to ensure interoperability with existing PBX systems and service provider requirements.

Usage recommendations

For reliable operation, deploy the device in a controlled environment with stable AC power and proper ventilation. Use both power inputs to enable redundancy, and schedule firmware updates and configuration backups as part of maintenance. Validate codec and fax passthrough settings when integrating legacy fax machines to ensure successful media transmission.
