Linksys SPA2102

The Linksys SPA2102 is an analog telephone adaptor which allows you to plug two standard phones into your broadband Internet connection or local area network allowing you to make VoIP calls.

Inexpensive, easy to install and simple-to-use, the Linksys SPA2102 connects a standard telephone or fax machine to IP-based data networks. IP telephony service providers and enterprises can offer residential customers traditional and enhanced communication services via a broadband connection to the Internet or Local Area Network (LAN).

The SPA2102 features two RJ11 POTS (Plain Old Telephone Service) ports for connection to existing analog phones, fax machines, PBX and key system communication platforms. Each SPA2102 telephone port can be independently configured via software controlled by the service provider and/or the end user. The SPA2102 also includes two RJ45 Ethernet ports. One Ethernet port connects to a broadband modem or router (WAN), while the other is an outgoing Ethernet port for connecting an additional PC or other device (LAN). Please note: The two ports are usually routed with NAT/firewall capability but can be used in bridged mode to connect in-line with a PC.

Stylish and compact in design, the SPA2102 can be used in consumer and business IP telephony service offerings including full-featured IP Centrex. The SPA2102 delivers clear sounding voice and reliable fax calling through its implementation of internationally recognized standards for voice and data networking.

The SPA2102 delivers clear, high-quality voice communication in a variety of network conditions. Excellent voice quality in challenging, changeable IP network environments is made possible via our advanced implementation of standard voice coding algorithms. The SPA2102 is interoperable with common telephony equipment like facsimile, voicemail, PBX/KTS and interactive voice response systems.

Note: This is an unlocked version of the SPA2102 and can be used with any provider or SIP compliant server.

1. Have been using this device for two weeks with 2talk.
   
   Configuring it was fairly simple by updating to latest firmware, and following directions on 2talk's FAQ page.
   
   Had a few issues getting it to work on my network, learned I had to use the WAN port with settings to use my router as the "gateway". Also had to ensure that "remote admin via WAN" was selected as well.
   
   Definitely a product for a technically inclined person, but once working, it's brilliant!

2. Thanks for your comment Mark. You're right that the Linksys ATA configuration can a little tricky - there's just so many options on those little devices.
   
   If anyone needs it feel free to contact me for a copy of the Linksys ATA Administration Guide. At something like 130 pages it's not for the faint of heart but pretty much everything is available in there.
   
   Cheers,

3. I have 3 analogue PABX systems (3 different sites) and would like to tie them together over our wireless IP network.
   Each site is within line of site of each other. I realise that we could use IP based PABX but maybe not just yet.
   Could I configure a ATA adaptors or similar to provide trunk lines between these systems, ie converts analogue to IP and back at the other end.
   For example - an extension on 1 system could be converted to IP, travel over the IP network then converted back to analogue and finally connected to an incoming trunk on another system.
   The reverse could also be employed for comma back the other way.
   This may take a few adaptors unless there is a multi trunk adaptors.
   
   Thanks

4. The SPA2102 can certainly be used as part of a solution to extend analog lines over IP. I would recommend looking at the ATCOM range of IP PBX units which do a good job of making up the other part of the solution.
