OnRelay has released its mobile PBX solution following successful trials in Europe, Asia Pacific and the Middle East.

Unified MBX is a software-only IP business communication system built for mobile phones.

The Cellular Fixed Mobile Convergence (FMC) provider said the solution provides Unified Communications (UC) without the expense of proprietary telephony hardware or IP PBX licenses.

It does so by pre-integrating cellular FMC software with an open source IP PBX.

The result is that Unified MBX can be deployed on-premises, or hosted in the cloud to provide mobile business communications as Software as a Service (SaaS).

OnRelay said customers across ten countries have so far self-installed the solution with only remote OnRelay support.

It is built around OnRelay’s Telephony Internetworking Protocol (TINP).

TINP uses voice and data signalling to bring full IP PBX functionality to the mobile phone, over any cellular network – 3G/GSM, EVDO and Low Power GSM.

In an interview with smartphone.biz-news earlier this year, Ivar Plahte, CEO and co-founder of OnRelay, said he had no doubt that mobile PBX is the future – with smartphones increasingly replacing desktop phones to become the sole business phone.
