MEDIAKIS MIC-420 DESCRIPTION:

The Ethernet Gateway is a next generation VoIP Gateway that provides a cost-saving solution for small business/home users on their telecommunication needs. The MIC-420ATA is following the open standard RFC-3261 SIP protocol to make sure that the user can easily install this device on most of the existing VoIP (Voice over IP) services. By using the state-of-the-art DSP (Digital Signal Processing) technology, the MIC-420ATA delivers outstanding voice quality that is very comparable to the PSTN voice quality.

With the built in LCD display, the user can easily configure the MIC-420 ATA for first time installation in a few minutes. And besides the advanced VoIP functions in easy installation, MIC-420ATA also provides flexible call out function between PSTN call and VoIP call through Ethernet or modem connection. MIC-420ATA is your best VoIP solution in the new generation communication.

FEATURES:

  • Choose between PSTN call and VoIP call :
    • The telephone set connected to MIC-420ATA can make either PSTN call or VoIP call easily.
    • When the MIC-420ATA is powered off, the connected telephone set can make PSTN call directly.
  • Following RFC-3261 SIP standard :
    • Support password authentication using MD5 digest and RFC-2833 for DTMF relay.
  • Dynamic IP support( DHCP and PPPoE) :
    • Getting Ip from DHCP server using DHCP protocol or through ADSL modem using PPPoE protocol, automatically reconnect when PPPoE lost connection.
  • Passing through NAT devices:
    • Support outbound-proxy configuration to make outgoing and incoming calls under any NAT devices (even under two layer NAT devices).
  • Remote software upgrade capability (via ftp):
    • FTP protocol provides reliable remote upgrade through Internet.
  • Advanced Digital Signal Processing (DSP) technology to ensure superior audio quality:
    • Hardware System on a Chip solution with built in DSP processor makes sure the perfect voice quality.
  • Support G.723.1 (6.3k/5.3k), G.729A/B, G.711(A-law/U-law) voice codecs :
    • Following ITU-T standard to support best compatibility.
  • Support Silence Suppression, VAD (Voice Activity Detection), CNG (Comfort Noise Generation) :
    • Silence suppression can save about half of the network bandwidth needed during normal VoIP conversation.
  • Ping function supported:
    • Ping other device in the Internet from MIC-420ATA to make sure the Internet connection is ok.
  • System status display on the LCD panel:
    • User can easily know if the MIC-420ATA is working normally and monitor the system status (network status, registering status) from the LCD panel display.
    • A “PKT Trace” function is supported to display the packets received on the LCD panel to let administrator find the network problem on line.
  • Call with or without proxy server (direct IP dialing) :
    • Following standard SIP protocol and is compatible with most of existing SIP Proxy server.
  • Provide easy configuration methods:
    • Very easy setting by keypads on the phone set.
    • Setting by web browser.
  • Support RFC-3261, TCP/UDP/IP, RTP/RTCP, HTTP, ICMP, ARP, DNS, DHCP, NTP/SNTP, FTP, PPPoE protocols
  • Interoperable with most of the existing SIP VoIP devices (IP-phone, gateway, proxy server) :
    • Please refer to the Interoperability List for the complete listing.
  • The LAN/WAN Port works for paralleled Ethernet cable and crossed Ethernet cable. HARDWARE SPEC
