Digium Positions Asterisk, Open Source PBX for Mid-Size Customers

Digium (promoter of Asterisk, the open source IP PBX) has launched the Switchvox 400 series. The new unified communications platform supports up to 600 users per system — meaning that Digium is attempting to march from the small business phone market into mid-market accounts. My big question: How does this latest on-premises push compare to Digium’s Switchvox Cloud solution, which launched earlier this year?
