Jasomi offers SIP repairs, so carriers don’t have to

Jasomi Networks has developed and integrated a Protocol Repair Engine into the latest release of its session border control product that fixes the most prevalent errors generated by phones and devices employing session initiation protocol (SIP).

The protocol repair engine is part of Jasomi’s Session Border Control for Far-End NAT Traversal product known as PeerPoint 3.0. It is designed to speed the introduction of new, mostly less-expensive SIP phones and analog terminal adapters (ATAs) by managing interoperability at the network level.

"We want to make it as easy as possible for a company to deploy VoIP with the best economics possible," said Benjamin Freedman, vice president of marketing at Jasomi. "That means using the cheapest phones or lower memory endpoints but not having to worry about all the nasty cross-platform issues."

PeerPoint 3.0 also helps service providers support multiple firewall revisions on the myriad of phones deployed in the network. Using the protocol repair engine, providers could avoid the need for every device to be upgraded if an error is discovered. Firmware also can be varied across geographies so that different encryption rules can be applied according to the regulations of other countries.

"We sell to a lot of Latin American VoIP companies that may have 20,000 phones out in the market and they don’t want to have to upgrade the firmware on all those phones. So we came up with a firmware update for their PeerPoint unit," Freedman said.

Less expensive phones and ATAs do not implement the full IETF RFC 3261 standard for SIP because of power or memory constraints. Jasomi’s PeerPoint will correct more than 30 protocol flaws related to less than complete implementations.

One very important error was found in Microsoft Messenger that wouldn’t allow it to work with several Internet service providers’ proxy servers. "That was a big problem because Messenger comes built in with Windows XP and provides a nice SIP phone on your desktop without having to buy anything else. We fixed that," Freedman said.

Jasomi also will announce as soon as next week another enhancement to its PeerPoint product called Media Path Optimization, which the company claims can save up to 93.5% call bandwidth utilization.

Media Path Optimization allows the media of a VoIP call--the content, not the signaling--to travel directly across the Internet or private network without having to traverse the service provider network. "It’s a huge cost savings for the service provider in terms of bandwidth," Freedman said. The company will demonstrate this new capability at the Spring VON Conference and Expo in March.
