While no one company can take credit for the Voice over IP (VoIP) revolution, perhaps no company has done more to make VoIP sound good than Sonus. Over 15 years ago, Sonus engineers developed the industry’s first carrier-class VoIP switch to bridge the old world (TDM) with the new world (SIP), and the rest is history. Today, the world’s leading VoIP providers are Sonus customers, and Sonus VoIP trunking solutions span the globe, delivering over one billion minutes of high-quality VoIP every day.
As service providers and enterprises make the shift to SIP-based communications, the need to bridge between legacy TDM and IP-voice is greater than ever. If your business still needs to “cut the cord” on expensive legacy switches, it’s time you connected with Sonus.
