The Mediatrix 4102S is a Security-Ready, VoIP gateway allowing Service Providers and Enterprise Networks to connect SOHOs, Remote Workers and Branch Offices to an IP network while preserving investment in analogue telephones and faxes. The Mediatrix 4102 offers security features such as SIP over TLS, SRTP, certificates management, and HTTPS designed to bring enhanced security for the network management, SIP signalling and media transmission aspects.
The Mediatrix 4100 Series provides a solution for the transparent integration of faxes, modems, point of sales and analog phones to IP Communication Systems. The 4100 Series are available in 2, 4, 8, 16 and 24 FXS ports designed to meet the varied application requirements of Service Providers.
The Mediatrix 4100 Series allow Service Providers to deploy rapidly and economically their solutions in medium-size enterprises as well as being the ideal solution for branch office connectivity to larger private networks.

Mediatrix 4102S Key Features
- Hardware ready to support Security (SIP over TLS, SRTP, MIKEY)
- Secured SIP signalling and media transmission
- Replacement of Mediatrix 1102/2102
- QoS features support
- DHCP client
- STUN Client
- Support for IPv6 Internet Protocol (Dgw v2.0 application)
It interfaces seamlessly with the full Mediatrix portfolio of products in secure networks. The Mediatrix 4102 also uses its innovative TAS (Transparent IP Address Sharing) technology and an embedded PPPoE client to allow the PC (or router) connected to the second Ethernet port to have the same public IP address, eliminating the need for private IP addresses or address translations. The 4102 also supports high compression codecs simultaneously on both analogue voice ports, saving valuable bandwidth.
