Digium, which sells a commercial version of Asterisk, customized it to integrate with Smart Cube’s software, making the phone system manageable via Smart Cube’s management interface.

Customers buy the Asterisk application from IBM’s Smart Market, and rely on IBM for support. Digium support staff is on call to IBM for tier 2 support, but customers only have to deal with IBM. 

The PBX software is sold in two sizes, for 20 concurrent calls ($2,000) and for 40 concurrent calls ($4,000).

Smart Cube is sold as a hardware platform with a base set of applications on it and a second set of applications available for customers to buy via Smart Market to address their specific business needs.
