The

The MediaPack™ 112, 114, and 118 are based on AudioCodes' field-proven and best-of-breed VoIP technology. Featuring 2, 4, or 8 analog ports, the gateways connect analog terminals, PBXs or key systems to the IP network using FXS or FXO connectivity. Compliant with multiple protocols including SIP, H.323, MGCP and MEGACO, the Analog Media Gateways enable flexible deployment and interoperability for the evolving next generation networks.
