AudioCodes MediaPack 1288 High-Density Analog Gateway – 72-Port FXS, Dual AC Power, SIP & T.38 Fax for Enterprise Use (MP1288-72S-2AC)

The AudioCodes MediaPack 1288 (MP1288-72S-2AC) is a high-density analog VoIP gateway configured with 72 FXS ports on a single FXS blade, with a redundant dual AC power supply. It supports SIP and T.38 fax relay, enabling organizations to migrate large analog phone and fax deployments to modern SIP-based VoIP infrastructure. The chassis accepts up to four FXS blades, so this 72-port configuration can expand to 144 ports (see MP1288-144S-2AC) as the deployment grows.

The Telecom Spot Take

The MP1288-72S-2AC is the starting point for large-scale analog migration when 144 ports are more than you need right now but a path to expansion matters. A single blade delivers 72 simultaneous analog channels — enough for a large floor, a mid-size campus building wing, or a government facility in a phased migration plan. The dual AC PSU provides the same redundancy as the fully loaded 144-port model: if one supply fails, the remaining PSU keeps all 72 analog lines active. For organizations planning a phased rollout — starting with one blade and adding more as PBX extensions are migrated — the expandable chassis design makes the 72S a smart initial investment rather than an undersized one.

Key Features

• 72 FXS analog ports — single-blade configuration for mid-scale analog-to-IP migration
• Dual AC power supply — redundant PSU keeps all 72 analog lines active if one supply fails
• SIP and T.38 fax support — analog phones and fax machines interoperate with SIP infrastructure
• Expandable to 144 ports — chassis supports up to 3 additional FXS blades without hardware replacement
• High-density chassis — 72 lines in a single rack unit, reducing space vs. multiple smaller gateways
