AudioCodes MediaPack Series MP-1288 - VoIP-Gateway

Legacy analog telephony infrastructure often becomes a costly bottleneck when migrating to IP-based communications. The AudioCodes MediaPack MP-1288 analog VoIP gateway bridges this gap by converting up to 72 analog phone lines into SIP or H.323 sessions, enabling seamless integration with modern IP-PBXs and unified communications platforms without replacing existing phones or wiring.

Who is it for

This gateway is ideal for enterprises, hotels, hospitals, and service providers that need to connect a large number of analog devices—such as phones, fax machines, and modems—to an IP network. It is particularly suited for organizations with centralized IP infrastructure and distributed analog endpoints, or those transitioning gradually from TDM to VoIP.

Main features

• High-density analog connectivity: supports up to 72 FXS ports for direct connection of analog phones and fax machines.
• Dual Gigabit Ethernet ports for network redundancy and failover.
• Comprehensive voice codec support including G.711, G.729A/B, G.723.1, G.722, and OPUS for flexible bandwidth management.
• Advanced fax handling with T.38 Fax Relay and G.711 Fax Pass-through.
• Robust security with SRTP, TLS, and HTTPS encryption.
• Redundant AC power supplies for high availability.
• 1U rack-mountable chassis for efficient data center or telecom room deployment.
• Management via Web GUI, Telnet, SSH, SNMP, and AudioCodes EMS for centralized control.

Tips

When deploying the MP-1288, ensure your IP-PBX supports the same VoIP protocol (SIP or H.323) and configure the appropriate codec to balance voice quality and bandwidth. For fax reliability, enable T.38 if your network has low latency and jitter. Use the dual Ethernet ports in link aggregation or failover mode to maximize uptime. Regularly update firmware via AudioCodes EMS to benefit from security patches and new features.
