OnRelay Opens Unified MBX Beta Program

Customers Invited to Test Drive Cutting Edge Software-Only Mobile PBX

OnRelay, the leading cellular Fixed Mobile Convergence (FMC) provider, today previewed its complete mobile PBX solution, Unified MBX, and opened the Unified MBX beta program to selected customers and innovative service providers. OnRelay’s Unified MBX software provides users with an advanced mobile office communication system (Mobile PBX), without the expense of proprietary telephony hardware or IP PBX licenses. Instead, SMBs and enterprise customers benefit from a low cost, feature-rich open source PBX, fully integrated with OnRelay’s proven FMC technology - delivering complete IP PBX functionality to the mobile phone. Unified MBX is highly flexible, supporting on-premises deployment, hosting, and distribution as software as a service (SaaS) by OnRelay’s partners. The only hardware required is a standard server or VMware instance, dramatically reducing the entry barrier for service providers relative to Centrex. As Unified MBX works over any public mobile network, users do not require WiFi, nor are they tied to one mobile operator or handset provider. “Unified MBX is the world’s first release of a true Mobile PBX – a fully fledged office communication system designed for mobile phones. Unlike the overly simplified Mobile Centrex approach, Unified MBX has all the user and management features expected from a business class communication system,” comments Ivar Plahte, CEO of OnRelay. “We are particularly proud of our new SIP based call flows that allow voice traffic to remain in the public network even for premises based Unified MBX servers.” Unified MBX integrates sipXecs, the leading open source PBX, to provide a scalable voice over IP (VoIP) system. Based entirely on the Session Initiation Protocol (SIP) standard, sipXecs brings an extensive feature set to Unified MBX, including active directory integration, presence and Microsoft exchange support. Customers can flexibly migrate user groups from legacy telephony hardware to Unified MBX, adding the Unified Communications features as required. “SIPfoundry fully supports efforts like that of OnRelay. We are enthusiastic that sipXecs is being used to develop innovative mobile telephony solutions,” comments Martin Steinmann, a member of the board of SIPfoundry, the open source community behind sipXecs. OnRelay’s Unified MBX beta program invites customers and service providers to trial Unified MBX in February 2009. - ENDS - Press contact Jane Johnston OnRelay +44 207 902 8143 Jane.Johnston@onrelay.com www.onrelay.com About SIPfoundry SIPfoundry is a fully independent not-for-profit open source organization. sipXecs is the largest open source effort around to build a unified communications system using the Session Initiation Protocol (SIP).
