SAN JOSE--Nationwide Internet access provider for business Bandwidth.com and super-regional integrated communications provider NuVox said this week they will use Sylantro System's application feature server to advance their respective voice-over-IP offerings.

Bandwidth.com, which serves more than 3000 business customers nationwide, is a source for purchasing, deploying and maintaining Internet and voice business products. The company's BandwidthVoice service can now connect multi-site company locations and remote employees with a single dialing plan, which creates a virtual campus environment.

In addition to Sylantro applications, the BandwidthVoice service incorporates solutions from lPeria, Convedia and Kagoor Networks. Bandwidth.com will use Iperia's ActivEdge unified communications applications for advanced integrated messaging services as well as Convedia's media server products and session border control solutions from Kagoor Networks.

NuVox Communications said it would use the Sylantro applications feature server platform for a VoIP offering across its 16-state footprint. NuVox is a privately held ICP that sells data, Internet, voice and other advanced communications solutions to more than 41,000 business customers across those states. The NuVox service comes in many forms, ranging from basic integrated-access service to advanced network-hosted services.

Sylantro serves Tier 1 providers, such as SBC and Swisscom, as well as smaller service providers.

"We designed our product to serve the largest providers in the world, like SBC and Swisscom, so naturally we can serve smaller service providers," Gutnick said.

Michigan-based VoEx was one of 11 service provider customers Sylantro signed up last quarter, Gutnick said. Sylantro also signed up national consumer VoIP provider SunRocket in November 2004 and has remained focused on the feature server space from the beginning. It is now beginning to pay off.

"We see more differentiation on application richness that cheap IP telephony services," Gutnick said.
