A TCO study including AudioCodes One Box 365
Many organizations that subscribe to Office 365 want Lync Enterprise Voice functionality, in addition to user-to-user voice and video, in order to enable calling to and from the Public Switched Telephone network (PSTN and cellular phones) and to enable PBX-like telephony features. To date, these organizations have had little or no data to determine the most economical way to enable Lync Enterprise Voice functionality. The authors of this TCO report have been analyzing and reporting on the total cost of ownership for adding Lync Voice capability to Office 365 for over a year and have now expanded that analysis to include the AudioCodes One Box 365 option.
Herein is a summary of the analysis of the total cost of ownership (TCO) of the recently expanded AudioCodes One Box 365 solution (50 users to 5,000 users) compared to other options for providing Microsoft Lync “enterprise voice” functionality either in combination with Office 365 or as a complete Microsoft Lync system on-premises deployment without Office 365.
The key takeaway from this independent, unbiased analysis performed by KelCor and UniComm Consulting is that, based on the available data and assumptions regarding costs and configurations,  the AudioCodes One Box 365 system used in conjunction with an existing subscription to the Office 365 E3 plan will be the most cost effective way to deploy Lync Enterprise Voice for organizations supporting between 50 and 5,000 users.
