Maintain analog services while moving voice traffic to SIP. The AudioCodes MediaPack 5xx MP508/8S/SIP gives infrastructure teams 8 FXS voice interfaces in a compact analog VoIP gateway designed for small-site deployments, targeted refreshes, and legacy endpoint retention. This model is well suited to branch offices and distributed locations where a handful of analog devices still need to stay connected: fax machines, elevator phones, paging systems, door entry lines, and emergency handsets. Instead of overbuilding with a larger chassis, the MP508/8S/SIP keeps the footprint focused on the exact port count required. For organizations managing mixed voice environments, it provides a clean bridge between analog endpoints and SIP infrastructure. That makes it useful when you need to extend the life of existing devices, reduce migration risk, and avoid unnecessary replacement costs. The result is a tighter deployment that supports current operations while the broader telephony environment continues its move to IP.
