Linksys SPA-2100

Our Price: $85.95

Inexpensive, easy-to-install and simple-to-use, the Linksys SPA-2100 connects standard telephones and fax machines to IP-based data networks. IP telephony service providers and enterprise users can offer traditional and enhanced communication services via the customers� broadband connection to the Internet or Local Area Network (LAN).

The SPA-2100 features two POTS (Plain Old Telephone Service) ports for connection to existing analog telephones, fax machines, PBX and key system communication platforms. The SPA-2100 includes an Ethernet interface for connecting to a home or office PC (LAN) as well as an Ethernet connection to the broadband modem or router (WAN).

Each SPA-2100 service line can be independently configured via software controlled by the service provider and/or the end user.

Installed by the end user and remotely provisioned, configured and maintained by the service provider, each SPA-2100 converts voice traffic into data packets for transmission over an IP network. Upstream voice traffic can take priority over less time sensitive data traffic to provide quality of service (QoS) treatment to VoIP phone calls.

Stylish and compact in design, the SPA-2100 can be used in consumer and business IP telephony service offerings including full-featured IP Centrex. The SPA-2100 delivers clear sounding voice and reliable fax calling through its implementation of internationally recognized standards for voice and data networking.
