Wireless security vendor Bluesocket has purchased open source IP PBX maker Pingtel, in hopes of creating a platform that will allow customers to inexpensively blend mobile and fixed wireless voice equipment.

With the acquisition, Bluesocket now has the technology to make devices for mid-size companies that quickly integrate wired, wireless and voice networks to streamline infrastructure.

According to Bluesocket, it plans to create such devices and provide them to other vendors on an OEM basis. Bluesocket will also extend this to small businesses that want to unify their voice and data networks based on standardised gear.

“The opportunity lies in the fact that the wireless LAN and unified communications markets are converging,” said Mads Lillelund, CEO at Bluesocket, in a statement. “As a result of this acquisition, we are better positioned to deliver an integrated solution that meets the mobility needs of customers across a variety of industries.”

The company says it will focus on handing off cellular phone calls to Wi-Fi networks and vice versa as a way for businesses to save on cellular costs when end-users make wireless calls within corporate campuses.

Bluesocket says it will continue support for Pingtel’s open source IP PBX, call-centre server and presence-server projects that all operate under the umbrella name SIPfoundry.

No Pingtel employees will be laid off, and according to Bluesocket, it will boost its research-and-development funding to reach its fixed/mobile goals faster.

Pingtel has not been alone in making its IP PBX software public. Competitor Digium has done the same with its Asterisk platform. With $13.8 million in venture funding, Digium is looking for partners that can customise and add to its core platform to develop systems that could replicate what Bluesocket is shooting for.
