From Telecomweb: Verizon Uses Recovery-Act Terms To Lure Enterprise Customers.
Under the American Recovery and Reinvestment Act of 2009, enterprises can take accelerated, or “bonus,” depreciation for voice and data gear ordered, invoiced and placed into service during 2009, and Verizon is urging enterprises to take advantage of this part of the Act. Verizon also sees the situation as part of its economic success story, given the current economy, thus the added financing incentives.
Other companies like EXCEL and Paetec are giving away PBX equipment with a SIP Trunk. It's these type of incentives that are creating sales growth in an otherwise tight market.
