The long saga of Callwave has ended, as the firm said this morning that it has officially changed its name to Fuze Box. The firm--which was for years one of Santa Barbara's most prominent technology firms--moved its headquarters to the Bay Area nearly a year ago, and recently went private, delisting from the NASDAQ. The firm went IPO in 2004. Fuze Box said it is now focused on online meetings and mobile collaboration; the firm said it still has offices in Santa Barbara.
