The Avaya G430 Media Gateway provides a cost effective , scalable, and secure platform for delivery of Avaya Aura™ Communication Manager-based IP telephony applications. It is targeted for small to mid sized branch offices or medium sized standalone businesses. Like other Avaya GX50 series Media Gateways, it can be configured to extend Communication Manager features and applications to branch offices at the edge of the enterprise network.

The Avaya G430 Media Gateway consists of a 1.5U high, 19" rack mountable chassis with DSP resources and memory. It has three Media Module slots that host a combination of interface boards to support T1/E1, ISDN-BRI, digital or analog telephones and analog trunks. The first Media Module slot can also host an S8300 Server to provide integrated IP Telephony for standalone businesses or mission-critical survivability for branch office-deployed G430s. The EM200 is 1.5 U high, 19" rack/desktop expansion unit for the G430 . it has two media module slots. Up to two EM200 can be connected to G430.

Important G430 capabilities include:

-Built-in interfaces include two 10/100 Base-T LAN ports, one 10/100 Base-T WAN port, two USB ports, services port, Contact closure adjunct port, Compact Flash slot for additional announcements storage.
-DSP Resources are available as fixed 20 channels on the G430. In addition a daughterboard can be added. The daughterboard can be implemented in 10, 20 or 80 channel . The maximum capacity is 100 channels. Codecs supported include G.711, G.729, and G.726.
-The G430 supports standard Local Survivability and Enhanced Local Survivability (with S8300 Server)
Basic routing capabilities including OSPF, RIP, and VRRP support. The G430 can also connect to an external WAN device via fixed 10/100 Ethernet WAN router port, which support traffic shaping to match data transfer rates with available WAN bandwidth.
Enhanced Quality of Service including Dynamic Call Admission Control for improved bandwidth utilization and Respond Time Report for better WAN monitoring
Advanced Security including VPN support, SRTP encryption, SSH/SCP, SNMP v3 support, secrets management.
