Description
If your business still runs analog phones, fax machines, or older PBX systems but you’re ready to move to modern SIP trunking or cloud voice services, the AudioCodes MediaPack 524 (MP524/24S/SIP) is built exactly for that job. This compact 1U gateway gives you 24 FXS ports so you can keep every legacy device working perfectly while connecting everything to your IP network. It’s perfect for enterprise branch offices, service providers, and any company that needs rock-solid voice without ripping out existing wiring.
The Telecom Spot Expert Review
What makes the MP524/24S/SIP stand out is its no-fuss reliability for real-world mixed environments. With native SIP support and proven interoperability (including Microsoft Teams SIP Gateway), it lets you migrate at your own pace instead of all at once. The built-in branch survivability keeps calls flowing even if the main network drops, and zero-touch provisioning means your IT team can deploy dozens of units without touching each one. Voice quality stays crystal clear thanks to advanced echo cancellation and multiple codecs. Whether you’re supporting a busy sales floor with fax machines or keeping elevator phones online, this gateway just works—quietly and dependably—while giving you the modern features your VoIP provider expects.
Please note: SBC sessions, Direct Routing Teams Integrations, high level features, and access to Audiocodes support may require an additional license or support contract.
