Nextel and ClickSoftware will jointly promote ClickSoftware's ClickSchedule and ClickMobile applications.

Field service professionals will have instant voice and data communication through Nextel Direct Connect and Nextel Two-Way MessagingSM to home office personnel and scheduling systems.
"Nextel has strengthened their competitive edge through the quality of its products and the responsiveness of its service," said Gary Fowler, Senior Vice President of Business Development for ClickSoftware. "We are confident that Nextel's customers access to ClickSchedule and ClickMobile will further differentiate Nextel's services from that of its competitors."
ClickSchedule is the premier scheduling optimization solution for medium and large service organizations. The application can be integrated with Customer Relationship Management (CRM) or other customer-facing systems to provide automatic scheduling of service personnel. ClickSchedule provides scheduling capabilities based on skills, location, customer contracts, travel time and other customer-specific business rules.
ClickMobile, a key component in ClickSoftware's suite of service chain optimization products, enables service representatives in the field to send and receive updated schedule information throughout the day. Through seamless integration with ClickSoftware's ClickSchedule, ClickMobile enables automatic, real-time rescheduling to ensure maximum efficiency and productivity.
ClickMobile enables service resources to interact with ClickSchedule via Nextel's Two-Way Messaging Service. With Nextel Two-Way Messaging, the user experience is very intuitive making it easy to send, receive and respond to messages. Nextel/ClickMobile interfaces wirelessly with the ClickSchedule application to adjust and optimize schedules dynamically in response to field user status updates.
"Nextel is one of the most respected and recognizable names in the telecommunications industry," said Dr. Moshe BenBassat, CEO of ClickSoftware. "This new relationship ties in perfectly with ClickSoftware's philosophy of partnering with only the highest-quality companies."
"We are very pleased to enter into this relationship with one of the premier developers of scheduling and optimization solutions," said Greg Santoro, Vice President of Internet and Wireless Services for Nextel. "The combination of our wireless services and ClickSoftware's applications will allow us to provide our customers with a powerful field service solution to maximize resources and raise customer service efforts to a new level of responsiveness.
