Mediapack 508 chassis

The AudioCodes MP508/4S4O/SIP is a VOIP gateway supplied as a Mediapack 5xx chassis. It provides analogue connectivity for voice-over-IP deployments and includes a single AC power input. The unit is intended for installers and IT teams building or extending SIP-based telephony systems.

Analogue trunk deployments

This gateway suits environments that need to connect legacy analogue handsets or fax devices to a SIP network. It is not for sites that require digital PRI or BRI interfaces, nor for installations demanding redundant power supplies or high-density port counts beyond the eight analogue ports this model provides.

Dual gigabit Ethernet ports

The product specifies one gigabit LAN port and one gigabit WAN port, allowing separate trusted and untrusted network segments. This dual-port design is the key specification that determines whether the gateway fits the planned network topology.

Questions about this item

How do I install the MP508 gateway and what wiring step is often missed?

Connect the single AC power supply, then link the gigabit WAN port to your router and the gigabit LAN port to the local network; the step often missed is verifying that the WAN port receives a DHCP address before registering SIP endpoints.

What maintenance will the MP508 need over time?

The unit has no user-replaceable fans or batteries; periodic maintenance is limited to checking AC power connections and applying firmware updates from the AudioCodes management portal.

Which limit appears first when the MP508 runs under sustained load?

The single AC power input is the first constraint; if the supply fails or voltage sags, all four FXS and four FXO ports lose registration simultaneously.
