        investment in telephones, conference speakerphones, and fax 
        machines as well as control their migration to IP with an 
        extremeley affordable, reliable solution. 
       Installed by the end user and remotely provisioned, configured and 
        maintained by the service provider, each SPA2102 converts voice 
        traffic into data packets for transmission over an IP network. 
        Compact in design, the SPA2102 can be used in consumer and business 
        VoIP service offerings including a full-featured IP Centrex 
        environment. The SPA2102 uses international standards for voice and 
        data networking for reliable voice and fax operation. 
    Includes Phone Adapter Unit, Power Adapter, Ethernet cable, Quick
      installation guide.
* Toll Quality Voice and Carrier-Grade Feature Support
   The SPA2102 delivers clear, high-quality voice communication in diverse 
   network conditions. Excellent voice quality in a demanding IP network is 
   consistently achieved via our advanced implementation of standard voice 
   coding algorithms. The SPA2102 is interoperable with common telephony 
   equipment like voicemail, Fax, PBX, and interactive voice response 
   systems.
* Large-Scale Deployment and Management
   The SPA2102 offers all the key features and capabilities with which 
   service providers can provide customized services to their subscribers.
