Austin, TX - November 27, 2006 - Global Crossing (NASDAQ: GLBC), a leading global IP solutions provider, and Dovetail Software today announced that Global Crossing has implemented the suite of Dovetail Software's service ticketing products. The suite is being used to support Global Crossing's Intelligent Front Office™ (IFO) initiative that provides e-bonding capabilities to Global Crossing customers.

With IFO, Global Crossing's enterprise customers and carrier Fast-Track customers can manage their networks down to the applications level and benefit more fully from a converged network. In addition, IFO lets customers and vendors interface directly with Global Crossing's systems from their own back offices, greatly simplifying network management processes and procedures.

Global Crossing's Fast-Track Services™ is a portfolio of wholesale business solutions that helps service providers increase their speed-to-market and revenue realization by expanding their geographic reach, broadening their range of converted IP service offerings, and providing a unified experience to their customers around the world. By using this strategic solution, service providers avoid costly expenditures and long lead times generally associated with service expansion.

Dovetail Software, formerly First Choice Software, was founded 11 years ago as a provider of software products and services for the Clarify® CRM user community, a Customer Service and Support CRM application purchased by Amdocs, Inc. in 2001. Dovetail CRM is a "thin client" application, which provides pure web-based remote access and does not require expensive plug-ins, third-party software, or extensive user retraining to implement and deploy.

"As we have implemented converged voice, video and data services over a single connection throughout our systems, Dovetail Software's ticketing generation system was the logical choice," said Barbara Switzer, Global Crossing's senior manager of applications programming. "Dovetail Software offered us a cost-effective and efficient solution that seamlessly integrates with our IFO initiative and Fast-Track Services."

Dovetail CEO Stephen Lynn, added, "While it is always great to establish strategic relationships with significant companies, such as Global Crossing, this relationship is particularly important in that it demonstrates to the market our ability to offer service providers a premier solution that offers them the greatest return on investment, while providing them and their end-users significant new functionality and performance."

Dovetail, formerly known as First Choice Software, was originally founded in 1995 to offer value-add solutions to customers using Clarify products. Given its focus on reducing the overall cost and complexity of Clarify CRM solutions, while improving performance, Dovetail has gained broad industry recognition from both Clarify and non-Clarify customers alike. Today, the company offers a comprehensive suite of CRM customer service and support solutions to improve customer retention, interaction, and satisfaction for customers using Clarify. Dovetail is headquartered in Austin, Texas. For more information please visit www.dovetailsoftware.com.
