The IP01 is a 1 port IP-PBX that runs Asterisk and uClinux on a powerful embedded Blackfin processor. To build an Asterisk IP-PBX you normally need a x86 PC plus a PCI card for the analog ports. With the IP01 you get all of that functionality in a tiny, low cost, low power, silent box.
Unlike many other embedded processors, the Blackfin has enough DSP horsepower to handle multiple channels of echo cancellation and speech compression. This means that the IP01 is a complete IP-PBX with 1 analog port. No PC required!
Easy to install, and simple to use, the Cisco SPA2102 Phone Adapter with Router connects a standard telephone or fax machine to an IP-based data network. Voice over IP (VoIP) service providers can offer residential and business users traditional and enhanced communication services via the customer's broadband connection to the Internet.
The SPA3102 features the ability to connect standard telephones and fax machines to IP-based data networks with the additional benefit of an integrated connection for legacy telephone network "hop-on, hop-off" applications. SPA3102 users will be able to leverage their broadband phone service more than ever by automatically routing local calls from mobile phones and land lines over to VoIP service providers and vice versa.
