Enterprises using Microsoft Office Communications Server 2007 now have the option of connecting directly to a global carrier-grade IP network to tap into managed VoIP services reaching 120 countries and delivered by early stage IP communications specialist Jajah Inc.

“As the SIP trunking provider for Microsoft Office Communicator Server, Jajah will provide full telephony capabilities to any Microsoft enterprise customer, anywhere in the world without the need for significant upgrades to existing infrastructure,” the company said.

Jajah launched in March 2006 with a web-activated calling consumer service and has since partnered with a number of carriers, telcos and technology companies to white label its services, and today partners with Deutsche Telekom, eHarmony, Plaxo, Jangl, IBM Lotus among others.

Trevor Healy, CEO of Jajah explained that the company is targeting four primary markets with its IP-based communications platform.

“We’ve addressed internet service providers as a vertical market, and so we already provide the back-end infrastructure for the Skype-out like Yahoo! Messenger call out service, and handle the call registration, connection and billing. We use the Jajah.com site to pull in SMBs who want IP communications served to them from the web off-premise. And we also deal directly with the telco channel.” 

With this latest announcement Healy said the company will begin to address large enterprise segments with a proposition that delivers IP telephony as a managed service.  

“Microsoft has defined the API that allows the Communicator instant message application to talk with our network. From there we have worked up a service that’s fully hosted, pay per use and delivers IP phones and IM Communicator at the desktop and provides features that allow IP calls to be made from a mobile or click-to-call links built inside an email or ERP sales order,” Healy told us.

 “The key point is that there is no upfront dollars, no capex and no heavy-lifting or infrastructure folk-lifting to be done,” he said.

The company’s SIP trunking services connect phone calls from computers, IP-phones and mobile phones to virtually any device in the world so voice calls can be made from any business computer or landlines.

The company is headquartered in Mountain View, California and has taken $30 million in venture funding from backers that include Sequoia and Intel.
