Integra Telecom Chooses Metaswitch to Support Customer Voice Network

Alameda, Calif., March 31, 2010 — Integra Telecom Inc. has chosen Metaswitch Networks to upgrade its voice service network. Integra is a facilities-based, integrated communications carrier operating in 11 western states. The company differentiates itself by staffing customer care, technical and account management professionals within each of the markets that it serves.

"While Integra serves markets across the West, we maintain a strong, local presence in all of our regions to ensure that our customers receive the highest standard of care," says Dudley Slater, CEO of Integra Telecom. "We consistently run satisfaction surveys asking our customers to rank the attributes they value most and it has never failed that reliability of service outranks all other attributes. Our decentralized business model is a clear reflection of our commitment to meeting the needs of our customers and we are pleased to partner with Metaswitch to exceed the expectations of our customers and enhance our service even further."

As a result of growth through acquisition, Integra Telecom has been operating on multiple software and hardware platforms. By partnering with Metaswitch to upgrade its voice services platform, Integra can now consolidate those systems therefore streamlining its network operations to better serve its customers.

"Most of the vendors we evaluated tried to make Integra fit into their product's capabilities," said Craig Heidgerken, vice president of engineering for Integra. "Metaswitch was willing to adapt to meet the unique needs of our company and we look forward to working with them moving forward."

Metaswitch could relate to that sentiment. "Our customers share the same values," said Mike Ward, senior vice president of sales at Metaswitch. "We believe in quality engineering, reliability, exceptional support and innovation and have built a business on providing the best solutions coupled with outstanding regional support. It's a perfect fit with Integra's business model."
