Move analog voice into a SIP environment without forcing a full endpoint refresh. The AudioCodes MediaPack 5xx MP516/16S/SIP is built for organizations that need a high-density FXS gateway to connect existing analog devices to modern IP telephony platforms. With 16 RJ11 voice interfaces, this model is well suited to sites where multiple analog phones, fax devices, or similar endpoints still need dependable service. It gives infrastructure teams a practical bridge for branch offices, migration projects, and mixed telephony environments where continuity matters. AudioCodes has a strong reputation in voice infrastructure, and the MediaPack line is aimed at deployments that value predictable interoperability and controlled rollout planning. That makes this gateway a sensible choice when you need to protect existing assets while standardizing on SIP. For organizations balancing cost, uptime, and migration risk, the MP516/16S/SIP offers a focused path forward: keep the endpoints that still work, connect them cleanly, and modernize the call platform on your schedule.
