Mitel TA 7108 Terminal Adapter

Mitel TA 7108 Terminal Adapter

The Mitel TA 7108 is a security-ready, VoIP terminal adapter, allowing analog phones and fax machines to connect to Mitel communications servers. In addition, the unit can act as a remote gateway with analog end-points via a WAN IP network to a central Mitel communications server.

The Mitel TA 7108 offers security features such as SIP over TLS, SRTP, certificates management, and HTTPS, designed to bring enhanced security for the network management, SIP signaling and media transmission aspects. It interfaces seamlessly with Mitel call servers in secure networks.

Product Overview

The Terminal Adapter Mitel TA 7108 comes with eight analog ports. Through the analog ports, the TA 7108 terminal adapters can connect up to eight analog phones, modems or faxes. In addition, a PC or home router can be connected to the units second LAN/Ethernet port.

For wide area connection, the terminal adapters use existing broadband access equipment to connect to any standards-based VoIP network. The TA 7108 offers security features, such as SIP over TLS, SRTP, certificates management, and HTTPS, designed to bring enhanced security for the network management, SIP signaling and media transmission aspects. The Mitel TA 7108 units interface seamlessly with the full Mitel communication system portfolio of products in secure networks.

The unit also use innovative TAS (Transparent IP Address Sharing) technology and an embedded PPPoE client to allow PC (or router) connectivity to the second Ethernet port. This is done to have the same public IP address as the first port, eliminating the need for private IP addresses or address translations. The Terminal Adapters support high compression codec’s simultaneously on all analog voice ports, saving valuable bandwidth.

For management purpose, the TA 7108 unites provide a web interface, giving administrator convenient access to the unit for initial setup. The devices can also be auto-provisioned by fetching their encrypted configuration from a TFTP or HTTPS server, making installation secure and transparent to end users.
