Businesses and ITSPs have long-needed an inexpensive way to connect legacy analog devices to a VoIP network, and Linksys announcement of the SPA8000 — an eight-port FXS Analog Terminal Adaptor device — early this year had many eagerly anticipating its release.

Finally, that time is here. The Linksys SPA8000 is expected to be available in the United States in early September.

We’ve been testing a unit Linksys made avaialble to us for several months, and see several different use cases:

  • As an ITSP Demark: ITSP’s can offer up to 8 independently configured analog lines;
  • Adding VoIP trunks to a legacy PBX: By connecting the Linksys SPA8000 FXS ports to the PBX trunks, that old PBX can now make VoIP calls;
  • Adding analog phones to a IP PBX: The most expensive part of a PBX upgrade is upgrading the phones, now upgrade the PBX, keep the phones, and upgrade over time.

The Linksys SPA8000 is a larger ruggedized departure from the usual Linksys SPA ATA form factor. The case is metal and desk or wall mountable, and looks like it belongs in a wiring closet.

The FXS ports can either be connected by eight RJ-11 jacks or an Amphenol (RJ-21) connector, as is more common in the wiring closet.

The unit also has the common SPA series routing capabilities, with 10/100 Ethernet WAN and LAN ports.

Our evaluation unit was an early prototype and did not include a cooling fan. The unit runs hot to the touch. The production version has a cooling fan and should run cooler.

The Linksys SPA8000 sets a new price point in the FXS gateway market. The cost of the Linksys SPA8000 is less than most competitors four port FXS gateways. Need more than eight FXS ports? Seriously consider buying multiple Linksys SPA8000, the price discount can offset the administrative overhead of multiple devices.

The Linksys SPA8000 will be very attractive to VoIP providers, multi-tenant environments, and businesses that want VoIP trunks without replacing their existing PBX infrastructure.
