As the market for SIP trunking heats up, service providers are increasingly turning to Metaswitch Networks. Carriers including Birch, LightBound and Fibernetics are finding that the feature richness, field-proven interoperability, and reliability of the MetaSphere platform enable them to differentiate their offerings and win in this increasingly competitive market.

The Metaswitch Business IP Trunking solution interoperates with a wide range of IP-PBX products while simultaneously supporting a rich, complementary set of hosted features that include voicemail, auto-attendant, find me follow me, and conferencing services.

A Metaswitch customer since 2005, Birch Communications is a Competitive Local Exchange Carrier offering voice and broadband communications services to businesses in 31 states. Birch Communications is using the Metaswitch Business IP Trunking platform to reduce trunking costs and lay the foundation to offer feature-rich services that were not possible in a legacy environment. Over the next 12 months, Birch Communications will complete its Metaswitch network migration to support SIP trunks for up to 80,000 lines.

Internet Service Providers that offer voice services are also benefitting from Metaswitch's Business IP Trunking. LightBound, the largest ISP in Indianapolis, uses SIP trunking to offer enterprise-class VoIP and disaster recovery services to healthcare organizations and commercial customers. Fibernetics, originally an ISP and now the fastest growing CLEC in Canada, recently completed a new build to specifically market voice services. Now in its fourth year with Metaswitch, Fibernetics offers SIP trunking services to enterprise end-users and wholesalers, with many customers receiving a positive return on investment in only eight months.
