Mediatrix 4100 Series VoIP Access Devices


Please call 877-877-2269 for a replacement product or part.
Extended Double Diamond™ Warranty Available (3 Additional Year)


  • Manageable through any standard Web browser or SNMP.
  • Support encrypted configuration files.
  • High-compression codecs on analog ports save bandwidth.
  • Compliant to current legacy standards for compatibility with PBX or Key systems.

  • Take advantage of Voice over IP while keeping your existing analog phones and fax machines! The Mediatrix 4100 series VoIP Access device enables you to save money by connecting these analog devices to VoIP across your IP network or the Internet. Its low price and ease of use make it ideal for applications in small offices and branch offices. Or use it for bringing VoIP to multi-tenant buildings.

    It's easy to install—just in plug your phones and fax machines and use your Web browser for setup. Mediatrix can also autoprovision by fetching encrypted configuration information from a TFTP, HTTP, or HTTPS server for a secure and transparent setup.

    Mediatrix 4100 Series VoIP Access Devices provide all basic phone features such as Call Forwarding, Call Transfer, Conference Call, and Call Waiting.

    An optional intelligent PSTN bypass can automatically switch your phone to PSTN analog phone lines when your power goes out, your network connection fails, or when you dial special numbers you specify—911 emergency, for instance.
