Comparing the TCO for 24 UC/IP-PBX Solutions

Comparing the TCO for 24 UC/IP-PBX Solutions The authors did an in-depth, apples-to-apples comparison of respondents to the Enterprise Connect 2012 mock RFP.

The authors did an in-depth, apples-to-apples comparison of respondents to the Enterprise Connect 2012 mock RFP.

One of the challenges organizations face is obtaining reliable cost data for UC and IP-PBX solutions and in being able to make apples-to-apples comparisons between them. Add the complexity of trying to compare on-premises to cloud to overlay deployment options, and the task of evaluating the numerous possibilities quickly becomes overwhelming.

To help make this task easier, 16 vendors offering a total of 24 solutions have shown vision and foresight by stepping up to respond to a mock RFP created jointly by David Stein of Stein Technology Consulting Group, Marty Parker of UniComm Consulting and UC Strategies, and Brent Kelly of Constellation Research. These solutions, covering cloud, overlay, and on-premises options* were presented at Enterprise Connect 2012 in Orlando last March.

The RFP was for 2,000 UC seats. The fictional organization consisted of a headquarters location and two branch offices. A 75-person call center was also included.

Based on the responses of the vendors themselves, and using only the public data presented, we have compiled the data into a format that makes it easy to compare the TCO over a five-year period for all of these solutions.

* These options were, specifically:

Option 1--Premises-Based (Private Cloud). Install a new IP PBX, including UC functions, on the enterprise premises.
Option 2--Cloud-Based or Fully Hosted. License and deploy PBX and UC functionality via a "Cloud" or hosted option, that is, any system servers and software will be hosted and run at the provider's site with only user devices and necessary gateways and similar equipment on the enterprise premises.
Option 3--Overlay or Side-by-Side. Install only the UC functionality so that it will co-exist Side-by-Side with the enterprise's existing TDM-based or IP-based PBX(s). Although overlay deployments can be implemented either on-premises or in the cloud, this report focuses only upon the on-premises option.
