The inability of our customers to successfully implement our signaling and network services with their existing systems could adversely affect our business.

Significant technical challenges exist in our signaling and network services business because many of our customers:

Customer implementation currently requires participation by our order management and our engineering and operations groups, each of which has limited resources. Some customers may also require us to develop costly customized features or capabilities, which increases our costs and consumes a disproportionate share of our limited customer service and support resources. Also, we typically charge one-time fees for initially connecting a customer to our SS7 network and a monthly recurring flat rate fee after the connection is established. If new or existing customers have difficulty deploying our products or require significant amounts of our engineering service support, we may experience reduced operating margins. Our customers’ ability to deploy our network services to their own customers and integrate them successfully within their systems depends on our customers’ capabilities and the complexity involved. Difficulty in deploying those services could reduce our operating margins due to increased customer support and could cause potential delays in recognizing revenues until the services are implemented.
