In case you missed the tweeting a few weeks ago, you should know that a new cloud offering for Unified Communications was launched by IBM (it's us) on April 16th. Under the name "IBM SmartCloud Unified Communications Dedicated", this offering delivers a complete communications suite from a private cloud. This solution is built on enterprise-grade software components, such as: feature rich telephony, instant messaging and presence from IBM Sametime and Sametime Unified Telephony, unified messaging from IBM, video integration, and more... A wide variety of communication devices can be made available with softphones, deskphones, and of course, support for smartphones and tablets.
This offering is designed to facilitate the transition to cloud-based telephony, and provides support for flexible deployment models (IBM data centers, or managed on customer premises). This offering is the result of an extended partnership between IBM Collaboration Services (Sametime software) and IBM Global Technology Services (ex: networking and managed services), aimed at delivering a best-of-breed and complete UC solution.
For more information, here is the official IBM announcement (www-01.ibm.com/common/ssi/cgi-bin/ssialias?htmlfid=897/ENUS613-002&infotype=AN&subtype=CA). You can expect more news around this new offering over the next few months.
