Description
If your business still relies on analog phones, fax machines, or older PBX trunks but you’re ready to move to modern SIP VoIP or Microsoft Teams, the AudioCodes MediaPack MP508/8S/SIP is the fastest, most cost-effective bridge you can buy. This compact 8-port FXS gateway gives you enterprise-grade voice quality, seamless SIP interoperability, and built-in security features that keep your legacy devices working perfectly on any IP network—without ripping out wiring or replacing handsets.
At The Telecom Spot we recommend the MP508/8S/SIP to any company with 8 analog devices that wants simple, reliable migration to VoIP or Microsoft Teams. Its dual Gigabit Ethernet ports and local survivability features make it perfect for branch offices that can’t afford downtime. Customers love the zero-touch provisioning that gets them online in minutes instead of hours, and the T.38 fax support that finally makes those old fax machines reliable again.
Please note: SBC sessions, Direct Routing Teams Integrations, high level features, and access to Audiocodes support may require an additional license or support contract.
