DALLAS - (Business Wire) - Sept. 21, 2005. CentricVoice, nationwide innovators of VoIP communications, today announced that the company has joined LignUp's FastLign Alliance and will provide the VoIP network components needed to enable LignUp's Hosted VoIP platform.

"We are excited about our involvement in the FastLign Alliance," stated Jeff Rothell, CentricVoice's CEO. "We are seeing explosive growth in the demand for Hosted Voice, especially in the SMB and enterprise markets. The agreement with LignUp provides us with a new sales channel. We look forward to providing local numbers, voice origination, termination, toll free service, and data solutions to partners who will be taking advantage of the FastLign Alliance."

Added Rothell, "We are well positioned to give partners that advantage of speed to market which they need to grab early market share, and that speed to market will allow them to jump start their own growth. We can currently provide VoIP service in 48 states, and that gives us and our partners a distinct advantage over other network providers who are capital constrained in building out a nationwide network for delivery of VoIP."

According to Kevin Nethercott, LignUp's CEO, "Until now, service providers have been required to build IP telephony services from the ground up, integrating often disparate technology and services in order to provide a complete solution. This has created a significant barrier to entry for service providers. With FastLign, service providers can take advantage of best-in-class services and software, which have been integrated, certified, and implemented by a managed services provider."
