Description
Twenty-four analog ports on a single IP connection — the AudioCodes MediaPack 124 is how enterprises and institutions migrate large numbers of analog devices to SIP without a forklift upgrade. Connect phones, fax machines, overhead paging systems, elevator lines, door-entry intercoms, or legacy PBX station ports directly to your SIP infrastructure, all managed from a single rack-mounted unit. The MP124/24S/AC/SIP runs on standard AC power and delivers the same enterprise SIP capabilities — T.38 fax, G.729A voice, zero-touch provisioning — that the MediaPack family is known for, at a density that makes it the right choice for whole-floor or whole-building analog integration.
The Telecom Spot Take
The MP124 occupies a unique position in the AudioCodes analog gateway portfolio: it's compact enough to sit on a shelf or in a half-rack, yet at 24 FXS ports it handles an entire wing of a building or a medium-sized office floor in one unit. Healthcare facilities use it to retain analog nurse call and emergency phone systems while moving to SIP for primary telephony. Universities deploy it in residence halls where analog phone connections are still contractually required. Hotels use it for in-room analog phones while routing over IP. The AC-powered version is the standard choice for environments with readily available AC outlets and no requirement for DC-powered telecom infrastructure. Zero-touch provisioning via TFTP or HTTP means IT teams can stage and configure units centrally, then ship directly to sites without needing a technician on-site at first boot.
Key Features
- 24 FXS ports (loop-start): Connect 24 analog devices simultaneously — phones, fax machines, paging systems, elevator phones, door intercoms, or PBX station ports.
- AC-powered: Standard AC power supply for environments without DC power infrastructure — no external converter needed.
- T.38 fax relay: Full Group 3 fax relay up to 14.4 kbps with automatic voice/fax mode switching per port — no separate fax gateway required for any of the 24 lines.
- G.711, G.723.1, G.726, G.727, G.729AB codecs: Expanded codec set including G.727 for maximum voice quality and bandwidth flexibility across 24 simultaneous channels.
- SIP RFC 3261 signaling: Full SIP support for hosted VoIP, on-premises SIP servers, and SIP trunking providers — plus H.323 and MGCP for legacy environments.
- G.168-2004 echo cancellation (128 ms): Clean, natural voice quality on every port regardless of analog loop characteristics.
- Zero-touch provisioning: Remote deployment via TFTP/HTTP — configure once at headquarters, ship units directly to sites.
- Stand Alone Survivability (SAS): Local call continuity during WAN or SIP server failures — no complete service blackout at the site level.
- Rack-mountable: Designed for 19-inch rack installation; rack mount kit sold separately (MP124RMK).
- SNMP and web management: Full enterprise network management integration with a browser-based configuration interface.

Frequently Asked Questions
- How many simultaneous calls can the MP124 handle?
- The MP124 supports up to 24 simultaneous voice or fax sessions — one per FXS port. All 24 ports can be active at the same time, each independently handling calls or fax transmissions.
- What's the difference between the AC and DC variants of the MP124?
- This SKU (MP124/24S/AC/SIP) uses an internal AC power supply — standard for most office and enterprise environments. The DC variant (MP124/24S/DC/SIP) is designed for carrier-grade and telecom facilities where -48V DC power is the standard infrastructure. Choose AC unless your site uses DC power distribution.
- Can I use the MP124 with Microsoft Teams or a cloud UCaaS platform?
- Yes, with an appropriate SBC in front of it. The MP124 connects to any SIP server or SBC. For Microsoft Teams Direct Routing, a certified SBC handles the Teams-side interface, and the MP124 connects to that SBC to bring analog devices into the Teams environment.
- Does the MP124 need a rack mount kit?
- The MP124 ships without rack ears installed. If you're mounting it in a 19-inch rack, order the MP124RMK rack mount kit separately — available from The Telecom Spot and installs in minutes.
