Description
Sixteen analog ports in a single compact unit — the AudioCodes MediaPack 124 in its 16-FXS configuration hits the middle ground between the 4-port desktop gateways and the full 24-port deployment. Connect phones, fax machines, overhead paging, elevator lines, or legacy PBX station ports directly to your SIP infrastructure with T.38 fax relay, G.729A voice compression, and zero-touch provisioning. The AC-powered variant is the standard choice for office and enterprise environments using conventional AC power.
The Telecom Spot Take
The 16-port FXS configuration is the right call when 24 ports is more than you need today but 4 ports clearly isn't enough. Mid-sized offices undergoing a SIP migration, healthcare practices retaining multiple analog lines, hotel floors with in-room analog phones — all of these map well to the 16-FXS density. The MP124 platform is the same across all port counts: same SIP/H.323/MGCP support, same zero-touch provisioning, same G.168 echo cancellation, same Stand Alone Survivability for WAN failover. You get enterprise gateway capability at a port count that matches your actual deployment without paying for capacity you won't use. Rack-mountable with the optional MP124RMK kit for clean, permanent installation.
Key Features
- 16 FXS ports (loop-start): Connects 16 analog devices simultaneously — phones, fax machines, paging systems, PBX station ports, or any FXS-compatible device.
- AC-powered: Internal AC power supply for standard office and enterprise environments — no DC power infrastructure required.
- T.38 fax relay: Group 3 fax relay up to 14.4 kbps with per-port automatic voice/fax mode switching across all 16 lines.
- G.711, G.723.1, G.726, G.727, G.729AB codecs: Full codec suite for optimal balance between voice quality and WAN bandwidth across 16 simultaneous channels.
- SIP RFC 3261 signaling: Works with hosted VoIP platforms, on-premises SIP servers, and SIP trunking providers; H.323 and MGCP also supported.
- G.168-2004 echo cancellation (128 ms): Consistent toll-quality voice on every port, regardless of analog loop length.
- Zero-touch provisioning: Deploy remotely via TFTP/HTTP — configure at headquarters, ship to site, gateway self-configures at first boot.
- Stand Alone Survivability (SAS): Local call continuity during WAN or SIP server failures.
- Rack-mountable: Designed for 19-inch rack installation; rack mount kit sold separately (MP124RMK).
