BandTel Launches N-Plus Solution

BandTel LLC, a provider of next-generation VoIP termination to the PSTN, on Monday launched its N-Plus architecture, designed to solve the throughput and redundancy problems on high-capacity SIP-based networks.

The N-Plus solution creates a clustered architecture that eliminates the need for numerous IP addresses on numerous SIP proxies. It also eliminates any single point of failure, according to BandTel.

"The telecommunications industry, especially VoIP, has changed dramatically over the past several years as has the use of VoIP on large networks. As the technology and uses of that technology evolves, we face more and more stumbling blocks that need to be overcome," said Peter Sandstrom, CTO of BandTel. "We recognized the problem facing high-bandwidth environments, so we took the initiative to develop our N-Plus architecture in an effort to help organizations with high-transaction SIP networks solve redundancy and failure problems by providing a truly cost-effective, fault tolerant solution."

The N-Plus network is based on several pairs of DNS servers that direct the SIP calls to SIP STPs, which also forward SIP calls within the BandTel SIP proxy matrix. This architecture allows BandTel to deploy a multitude of SIP proxies (N-Plus) that handle call loads to any end point. There is no processing limit and no need for the user agents to hard code a carrier's proxy address into their network configuration schemas, the company said.

To address issues related to registration and routing information, BandTel created synchronization and registration services, which run redundantly in real time, keeping registration and routing information current and equal across all BandTel proxies.
