Los Angeles-based PBX provider Fonality has scored a win in London, the firm said earlier this week. Fonality said that Top Gear Cars, which provides independent taxi service in the London-metro area, will use the firm's Fonality trixbox Pro business phone system. Size of the deal was not announced. Fonality is a provider of PBX software based on open source. The firm is venture backed by Draper Fisher Jurvetson Growth Fund, Intel Capital, and Azure Capital Partners.
