IRVING, Texas, Oct. 24, 2012 /PRNewswire/ -- BT today announced the availability of BT One Cloud for Microsoft Lync, a cloud service based on Microsoft Lync 2010, providing instant messaging, presence, audio, video and web conferencing, and Enterprise Voice. Offered on a monthly 'pay-per-user' basis, BT's new service provides high performance unified communications without significant capital investment. A recent survey from BT found that 62 per cent of global executives want integrated instant messaging and email and that 68 per cent want cloud-based file services to be able to collaborate more easily internally and externally. To give executives the tools they need, the new BT cloud offering is designed to provide the full functionality of a premises-based Microsoft Lync deployment, but packaged as a commercially-attractive cloud-based service. BT has partnered with industry leading audio, video, and gateway device vendors supporting a holistic and end-to-end solution approach. The fact that BT has both on-premises and cloud variants of Microsoft Lync in portfolio, means that customers have a choice and that BT can accommodate a variety of hybrid service models where required. For clients with existing multi-vendor investments in telephony, video, and other unified communications infrastructure, BT offers Hybrid Architecture Services consulting engagements to develop the appropriate roadmap for Microsoft Lync migrations and deployments. Customers can also elect to attach BT's enterprise grade voice and reap maximum Microsoft Lync functionality or start more simply and hold Enterprise Voice within their roadmap. BT has already completed its first sale of BT One Cloud to a global energy company where BT will design, install, and integrate the service for 10,000 Microsoft Lync seats globally. That service will incorporate instant messaging and presence in addition to audio, video, and web conferencing. The service will also deliver full Enterprise Voice functionality to the entire user population, initially in the US and then globally, providing a full PBX replacement service for the customer.
