The Mediatrix 4124 access devices are high-quality and cost efficient VoIP gateways connecting larger branch offices and multi-tenant buildings to an IP network, while preserving investment in analog telephones and faxes. The Mediatrix 4116 access devices allow Service Providers to deploy rapidly and economically their solutions in medium-size premises and they are the ideal solution for branch office connectivity to larger private networks. The Mediatrix 4124 connects up to 24 analog phones and/or faxes to a broadband modem or LAN.

The Mediatrix 4124 has the additional benefit of supporting high compression codecs simultaneously on each analog voice ports, thus saving valuable bandwidth. As all other Mediatrix devices, the 4124 provides a web interface, giving users a convenient access to the unit for initial set-up. The devices can also auto-provision by fetching their encrypted configuration from a TFTP or HTTP server, making installation secure and transparent to the end-users. To further facilitate deployments, factory-loaded configurations are possible. In addition, an optional intelligent PSTN bypass allows Mediatrix 4124 users to make emergency calls and maintain their phone service in the event of a power outage or network failure.
